2011/18: Are speed cameras effective?


What they said...
'I have no compunction in calling speeding fines a form of taxation because any examination of how they work leads to that conclusion'
Paul Murray, former editor of the West Australian

'There is a causal link between speed and severity of a crash'
Victorian Auditor General's report, 2011

The issue at a glance
On October 3, 2011, it was announced that an extra 32 speed and red-light cameras would be progressively switched on across Melbourne from the following day.
The Victorian Police Minister, Peter Ryan, noted that the Auditor-General's report released on August 31, 2011, had found Victoria's camera program reduces road trauma. Mr Ryan claimed these findings had convinced the government of the effectiveness of speed cameras.
The decision has created controversy as speed cameras are unpopular in Victoria and some members of the current government, when in Opposition, had suggested that these cameras were used primarily for revenue-raising purposes.
Road traffic authorities generally support the use of speed cameras while a range of motorist lobby groups oppose them. The cameras have received a very negative treatment from a number of media outlets.
A debate similar to that in Victoria has occurred in New South Wales, where in July, 2011, the New South Wales Roads Minister, Duncan Gay, ordered that 38 speed cameras across the state be switched off immediately after an audit found that they were not improving road safety.
Despite this, the New South Wales Auditor General stated that generally, 'speed cameras change driver behaviour and improve road safety'.

Background
(The following is an edited version of two wikipedia entries, one titled 'Traffic enforcement camera', and the other, 'Road speed limit enforcement in Australia'. The full text of these entries can be found at HERE and HERE)

Traffic enforcement cameras
A traffic enforcement camera (also referred to as a speed camera, red light camera, road safety camera, road rule camera, photo radar, photo enforcement or Gatso) is an automated ticketing machine. It may include a camera which may be mounted beside or over a road or installed in an enforcement vehicle to detect traffic regulation violations, including speeding, vehicles going through a red traffic light, unauthorized use of a bus lane, for recording vehicles inside a congestion charge area.
The latest automatic number plate recognition systems can be used for the detection of average speeds and raise concerns over loss of privacy and the potential for governments to establish mass surveillance of vehicle movements and therefore by association also the movement of the vehicle's owner. Vehicles owners are often required by law to identify the driver of the vehicle and a case was taken to the European Court of Human Rights who found that the Human Rights Act 1998 was not being breached. Some groups, such as the National Motorists Association in the USA, claim that systems "encourage ... revenue-driven enforcement" rather than the declared objectives.

Road speed limit enforcement in Australia
Road speed limit enforcement in Australia constitutes the actions taken by the authorities to force road users to comply with the speed limits in force on Australia's roads. Speed limit enforcement equipment such as speed cameras and other technologies such as radar and LIDAR are widely used by the authorities. In some regions, aircraft equipped with VASCAR devices are also used.
Fixed speed-only cameras are among the most commonly used. These cameras come in many forms, some free standing on poles; others mounted on bridges or overhead gantries. The cameras may consist of a box for taking photographs, as well as a smaller box for the flash, or only a single box containing all the instruments. Recently introduced infrared cameras, do not emit a blinding flash and can therefore be used to take front-on photographs showing the driver's face.
Most states are now starting to replace older analogue film fixed cameras with modern digital variants. Fixed speed cameras can use Doppler RADAR or Piezo strips embedded in the road to measure a vehicle's speed as it passes the camera.
However ANPR technology is also used to time vehicles between two or more fixed cameras that are a known distance apart (typically at least several kilometres). The average speed is then calculated using the formula speed = distance/time. The longer distance over which the speed is measured prevents drivers from slowing down momentarily for a camera before speeding up again. The SAFE-T-CAM system uses this technology, but was designed to only targets heavy vehicles. Newer ANPR cameras in Victoria are able to target any vehicle.
Trials of mobile speed cameras began in the state of Victoria in 1985. The cameras were placed, with warning signs, at sites with a history of frequent crashes. Although the cameras influenced traffic speeds up to two kilometres from the site, there was no statistically significant impact on the crash numbers found. Later warnings were removed and the effect on crash numbers appeared greater.
Mobile speed cameras were first used in New South Wales in 1991. In 1999 the authorities began to install fixed cameras, and signs warning of their presence, at crash black spots. The government of Western Australia started using speed cameras in 1988.

RoadWatch is an Internet site established 'to help motorists voice their opinion on all things road-related. The focus is often on speed cameras.' The site is generally opposed to speed cameras. It can be accessed at http://www.roadwatch.com.au/forum/default.asp

Arguments against speed cameras
1. Speed is not a major component in accidents
Opponents of speed cameras claim that the importance of speeding as a contributory factor in road accidents has been exaggerated.
The lobby group RoadSense, which is opposed to the general introduction of speed cameras, notes a 1994 report produced by the Queensland Government Parliamentary Travelsafe Committee. The report is said to include the claim that 'Fatal accidents, caused solely by speed, represent 1.8% of all accidents reported State-wide, but only 0.8% of all accidents in Brisbane.'
RoadSense then condemned motorist associations across Australia for not opposing speed cameras on the basis of inadequate evidence that speed kills. RoadSense states, 'We have to question whether our motoring associations were looking out for their members interests when speed camera legislation was passed...We call on our motoring associations to question the data used for the justification of speed cameras.'
Another motorist lobby group, CarAdvice, also opposed to speed cameras, argues similarly that speed is not a significant contributory fact in road accidents. The group cites a 2006 United Kingdom Department for Transport study titled Road Casualties Great Britain. The report studied 145,798 road collisions over the previous year and stated that '"Exceeding speed limit" was attributed to 3 percent of cars involved in accidents.'
The United Kingdom Department for Transport study also stated, 'The most common factor is failure to look properly which contributed to 35 percent of accidents. Four of the six most frequently reported contributory factors involved driver or rider error or reaction.'

2. Speed cameras do not affect driver behaviour positively
It has been claimed that speed cameras have little or no positive influence on driver behaviour.
The lobby group CARR (Citizens Against Road Ripoffs), which opposes speed cameras has stated, 'Like police radar traps and unmarked police cars, these cameras are very obviously revenue raisers and do nothing whatsoever to make the roads safer. This is easy to prove by simple logic. Motorists do not get any indication when they are booked by fixed cameras.
The infringement notices can take anywhere from three weeks to two months to arrive. Therefore motorists have nothing to indicate that they should modify their driving practices for the often lengthy time between the actual infringement and the arrival of the infringement notices.'
CARR elaborated its position further, giving the following hypothetical example, 'A motorist who is booked driving over the limit by a speed camera may continue at that excessive speed, totally oblivious to the fact that he has been booked and may very well kill a number of people in an accident well before that infringement notice arrives to indicate that his behaviour was dangerous.'
A commentator emailing the Geelong Advertiser on February 8, 2011, shared this view. He stated, 'The key is to improve driver behaviour and ability to avoid collisions, not just fixate on penalising speed. With no immediate obvious connection between committing a driving offence and its punishment, the deterrent effect is virtually zero, as with "safety" cameras.'
The new Liberal Coalition government in Victoria also seems to hold the view that speed cameras would have a greater deterrent effect if motorists knew where they were. In February 2011, the Government began regularly publishing speed camera locations.

3. Speed cameras are often inaccurate
There have been a number of successful challenges to speed-camera-imposed fines which have contributed to the view that speed cameras are inaccurate.
In February 2011, a magistrate upheld Leading Sen-Constable Trevor Bergman's appeal against a $250 speeding fine, ruling that the senior constable was legally within the speed limit on the stretch of road where he was caught. (It needs to be noted that this case did not cast doubt on the accuracy of the speed camera that detected Sen-Constable Trevor; the issue was with the speed limit signage.)
In October, 2011, Policewoman Faye Pitman had a speed camera fine dismissed when a magistrate accepted her word and that of a passenger that she w as driving at 98km/h on EastLink when the camera snapped her at 106km/h.
The Herald Sun reporter writing on the Pitman case speculated that it would further undermine faith in the cameras and that, 'Unless there is a successful appeal against the word of Senior Constable Pitman and her witness, hundreds of speed camera fines are likely to be contested.'
Legal experts and police officers have also suggested that the Pitman case could lead to many others like it. One officer stated, 'This could open Pandora's Box for everyone else.'
Barrister Michael commented, 'It's a really great thing. Previously, it has been impossible for people to prove that they weren't speeding. It means there will be a floodgate opening of people challenging, and many, many more people and angry drivers questioning their fines.'
Another barrister, Theo Alexander, has said the decision would likely 'embolden many motorists who have been charged in similar circumstances to challenge their speeding fine'.
The Victorian Auditory General's report on the effectiveness of speed cameras released at the end of August, 2011, stated, 'Two major faults in the road safety camera system have raised doubts about the integrity of the program for some sections of the community and the media. Incorrect infringements from the Western Ring Road cameras in 2003 and the Hume point-to-point cameras in 2010 have been subject to significant public comment.'

4. Speed cameras are essentially a revenue-raising device for governments
There is a wide-spread belief that speed cameras are primarily intended as revenue-raisers for governments, rather than as a means of reducing the road toll. Some critics argue that the proof of this is that, in Victoria at least, the locations of speed cameras were not advertised.
There are those who claim that Victoria's relatively large number of speed cameras and the fines they generate are essentially a form of differential taxation on road users.
In an article published in The Herald Sun on November 24, 2010, the following claims were made, 'Victoria is the only state in Australia that does not put up signs to warn motorists they are approaching a fixed speed camera.
Mobile speed cameras in some Australian states also have warning signs. But Victorian motorists are not warned they are approaching a mobile speed camera.
Victoria has by far the highest cash penalties in Australia for speeding at less than 10km/h over the limit and Victorian motorists also pay the most for exceeding the speed limit by more than 10km/h but less than 15km/h.' The implication of these observations is that the Victorian Government was seeking to maximise the revenue-raising potential of these cameras.
In an article published in The Herald Sun on December 27, 2010, Ashley Gardiner stated, 'Only four of Victoria's 20 most dangerous accident black spots are monitored by speed cameras. Yet almost all of the most lucrative speed camera locations have been free of fatalities in the past five years.
Dangerous outer-suburban intersections are being ignored in favour of busy inner-city locations. The revelations have been seized on as proof that cameras are for revenue raising.'
The claim that speeding fines are primarily a revenue source for governments has been made overtly by Paul Murray, former editor of the West Australian. Mr Murray has stated, 'I have no compunction in calling speeding fines a form of taxation because any examination of how they work leads to that conclusion.
There is no victim other than the driver when you are snapped for doing something like 5kmh over the speed limit. So it is hard to see the fine as a punishment when there's been no offence against anyone.
The majority of speed camera fines are for low-speed offences. They are therefore such a small relative penalty as to be useless in changing behaviour. So, in my view at least, speeding penalties have more in common with a road use fee than a punishment. They are more of a tax than a fine.'

5. Speed cameras can cause accidents
There are those who claim that speed cameras can actually increase the risk of an accident.
A report was issued in August 2011 by the insurance company Liverpool Victoria (LV=) on a survey conducted among 1,532 of its members on the effects of speed cameras on driver behaviour.
The poll found 81 percent of drivers said they looked at their speedometers rather than the road when a camera came into view, the poll by insurance company LV= revealed. While five percent admitted to braking suddenly when in sight of speed cameras, risking rear-end shunts.
A further 31 percent claimed to have witnessed an accident, or a near-miss, as a result of drivers' erratic behaviour when faced with a camera. 46 percent of those surveyed believed that cameras diverted attention away from other areas of their driving, while 11 per cent believed cameras actually increased the risk of an accident.
The managing director of Liverpool Victoria, John O'Roarke, stated, 'The feedback from drivers is that while.,. [speed cameras] may reduce speed, they also appear to impair driving ability or, at the least, concentration on the road. As this report shows, some drivers behave erratically and, at worst, dangerously, around speed cameras.'
Brian Gregory, a spokesperson for the Association of British Drivers has claimed, 'No more than six per cent of accidents in this country are caused by speeding drivers...Most accidents are caused because drivers are unable to concentrate on the road because they are looking for cameras.'
The Australian lobby group CARR (Citizens Against Road Ripoffs) has also claimed, 'Speed cameras may even cause accidents because journey times are increased, causing drivers to become frustrated. Drivers may divert to less safe routes to avoid cameras and cameras can distract driver attention, and cause sudden braking.'

Arguments in favour of speed cameras
1. Speed is a major contributory factor in causing and worsening road accidents
There have been a wide range of studies done which indicate a connection between speed and accident rates. None of these studies appear to claim that speed is generally the sole contributory factor; rather they are look at the effect of speed in connection with the mix of other factors that affect car safety and driver performance.
A 2002 British study prepared for the Road Safety Division, Department for Transport, Local Government and the Regions by Taylor, Baruya and Kennedy found that 'Accident frequency in all categories increased rapidly with mean speed. The "All accident frequency" increased with speed to the power of approximately 2.5 - thus indicating that a 10% increase in mean speed results in a 26% increase in the frequency of all injury accidents.'
The same study found that the effect of speed was particularly negative under adverse road conditions, for example, where there are frequent sharp bends or intersections.
The study report stated, 'The effect of mean speed was found to be particularly large (power of about 5) for junction accidents, suggesting substantial potential for accident reduction from strategies designed to reduce speeds at junctions.'
Studies of fatal road accidents in rural Australia have indicated that speed is a major contributory factor. The 1995 Henderson study noted that excessive speed 'not only makes crashes more likely, it makes the crashes that do occur more destructive'. The 1999 Kloeden et al. study demonstrated that excessive speed leads to more driver errors and gives drivers less reaction time. A 1995 Victorian case-control study of fatal single-vehicle crashes found that driving above the speed limit significantly increases the chances of involvement in a road crash.
Australian studies indicate that excessive speed is a probable or possible cause in 25% of the rural crashes around Adelaide (Kloeden et al. 1997) and is a factor in up to 36% of fatal crashes in NSW (Department of Transport, 1998).
The recent 2011 Victorian Auditory General's report on the effectiveness of speed cameras commented on the effect of speed under all driving conditions, rural and metropolitan. The report stated, 'The link between speed and the likelihood of a crash is strongly supported by research evidence.
A seminal study conducted in 2001 by the University of Adelaide found that in rural
areas in South Australia, the risk of crash doubled with a 10 km/h increase in speed in
100 km/h zones. Another study by the same university conducted in 2002 found that in metropolitan areas, when travelling between 60 and 80 km/h, the vehicle occupants' risk of a fatality or serious injury crash doubled for each 5 km/h increase in travelling speed. As such, small increases in speed have significant impacts on crash risk along with more excessive speeding.'
Referring specifically to the effect of speed on the severity of an accident, rather than its contribution to the likelihood of an accident, the Victorian Auditor General's report stated, 'There is a causal link between speed and severity of a crash, because when a crash occurs, the greater the travelling speed, the greater the impact energy which is transferred to the road users involved.
In a head-on crash, the likelihood that occupants will survive decreases rapidly if the
vehicle is travelling above 70 km/h. For side-impact collisions, the chance of survival decreases rapidly above 50 km/h.'

2. Speed cameras reduce speeding and accidents
There have been a wide range of studies which have demonstrated speed cameras reduce both speeding and accidents.
On October 6, 2011, Dr Ananya Mandal reported in News Medical on the findings of recent study conducted by the University of Queensland. The study analysed 35 other studies from Australia, the United States, Canada, Germany, Denmark, Finland, Britain, Hong Kong, the Netherlands, New Zealand and Norway to determine the usefulness of speed cameras in preventing accidents.
Collated findings from all the studies showed that speed cameras cut the average speed by 1-15 percent and the percentage of vehicles that exceeded local speed limits between 14 percent and 65 percent. The numbers of crashes in the areas of the cameras also fell by between 8 percent and 49 percent, while fatal or serious injury crashes reduced by between 11 percent and 44 percent.
Researcher Cecilia Wilson of the University of Queensland's Centre on National Research on Disability and Rehabilitation Medicine stated, 'While there is variation in the results, the overall finding is clear - speed cameras do reduce injuries and deaths...Even though some of the studies were not conducted as carefully as others, the consistency in the way that vehicle speeds, crashes, road traffic injuries and deaths all reduced in places where speed cameras were operating shows that these cameras do a good job.'
The University of Queensland study concluded, 'Speed cameras used for road section control, which measure average speed over distance, together with related emerging technologies arguably have the potential to favourably influence speeding behaviour and thus enhance road safety.'

3. Speed cameras are generally accurate
Supporters of speed cameras typically stress their accuracy and the quality of their maintenance program.
The Victorian Auditor General's report notes that faults are infrequent and rapidly rectified. In 2010, a software fault in the Hume point-to-point camera system resulted in nine infringements being incorrectly issued. On Thursday 14 October 2010, a police officer went to serve a notice for vehicle impoundment arising from a speed infringement on the Hume Freeway. The officer reported to the Traffic Camera Office that he thought that the driver was unlikely to have committed the offence.
On Friday 15 October, the Hume system was retrospectively deactivated as from Thursday14 October. A review of infringements was initiated on the same day and completed by the morning of Monday 18 October. The review examined infringements detected around the times at which cameras in the system resynchronised their internal clocks as this was identified as the most likely cause of inaccurate readings.
The Department of Justice then reviewed all infringements since activation of the system in 2007. Both the first and second reviews identified the same nine incidents as invalid. The total number of infringements issued since activation of the system in 2007 was around 68 000. The nine invalid infringements were withdrawn.
Regarding the maintenance of fixed speed camera's the recent Victorian Auditor General's report further stated, 'The maintenance and testing program for fixed cameras is comprehensive, methodologically sound and undertaken at appropriate intervals. This is complemented by a strong systematic approach to monitoring the fixed camera network for faults and equipment degradation.'
The Victorian Auditor General's report also noted that the Department of Justice receives information on the condition of the camera network at daily, monthly and quarterly intervals. In addition to information received from regular scheduled maintenance and testing activities, sources of information about possible faults are daily electronic monitoring of the status of cameras providing alerts of power or communications failure, or gross faults in camera image; monthly report of camera system performance and reports from the public or Victoria Police of camera faults providing observations of cameras' physical condition.

4. Speed cameras are not essentially revenue-raising devices
It has been claimed that speed cameras are not about revenue-raising but are put in place to alter driver behaviour and increase road safety.
The Victorian Auditor General's report notes that speeding fines provide the government with less than .5 percent of its annual revenue. The report also notes that implementation discretion, which means that many possible fines are not actually applied, saw the Victorian Government deliberately forfeit $8.4 million in fines over the last financial year.
In relation to the claim that there are too many cameras and the fines are too high, the Victorian Auditor General's report claims that for speed cameras to be effective they have to be widespread and the fines need to be significant.
The Auditor General's report states, 'The extent to which enforcement is effective depends on the level of perceived risk that it can create. To create a high level of perceived risk, a significant number of road users and a significant amount of the road network must be exposed to enforcement. If enforcement is too small, is reduced, or is removed, the perceived risk will fall and there will be less deterrence. As such, to be effective, enforcement activities must be ongoing and of sufficient scale.'
The Victorian Auditor General's report also states that there is no documentary evidence from any relevant government department to indicate that revenue raising is a factor in the decision as to where speed cameras will be placed or in the decision about the level at which fines will be set. The Auditor General's report claimed that all available evidence indicates that the basis of these decisions is preventing road accidents.
Defenders of speed cameras claim the fact that Victoria did not (until recently) warn motorists of the location of cameras was a road safety measure, not a revenue-raising one. They argue that warning drivers of the location of speed cameras reduces their overall effectiveness. A warning may ensure that drivers slow down in the vicinity of the marked cameras; however, there is unlikely to be any effect on driving behaviour in areas where there are no cameras.

5. Opposition to speed cameras is media-driven and sometimes politically motivated
It has been suggested that public opposition to speed cameras has been fuelled by the negative treatment they frequently receive in the media. It has further been suggested that there is frequently no factual justification for the negative nature of these reports.
This point has been made by the Victorian Attorney General's report which stated, 'Public confidence in the reliability and accuracy of the road safety camera program has been...undermined by the media reporting surrounding the high amounts of infringements on the EastLink Freeway, although there has been no evidence of incorrectly issued infringements.'
It has been claimed that the current Victorian government, when in Opposition, used community dislike of speed cameras as a way of discrediting the former government.
Josh Gordon, in an article published in The Age on September 8, 2011, stated, 'In 2009, the then shadow and now Minister for Roads, Terry Mulder, said speed cameras represented a "treasured pot of gold for John Brumby".'
Gordon also claims, 'During last year's election campaign, Ted Baillieu promised a government led by him would regularly publish details of mobile speed camera locations, while hinting there were serious questions about their placement being linked to raising revenue.'

Further implications
Speeding fines and the operation of speed cameras are a highly emotive issue. TAC surveys conducted in 2009 indicated that 59 percent of those surveyed believed the cameras were primarily a revenue-raising device. A similar survey conducted the next year showed the number had risen to 69 percent. Scepticism within the community regarding speed cameras appears to be very high.
The most recent Victorian Auditor General's report on the operation of speed cameras suggests that negative media coverage contributes to the popular perception that the cameras are either faulty or are primarily revenue-raisers for governments. Clearly there is no story in reporting that a speed camera worked effectively or that hundreds of thousands of people across Australia acknowledge they were speeding and pay their fines without complaint, if unhappily. However, the almost entirely negative focus in the media on the operation of speed cameras can have unfortunate consequences.
There are those who argue not only that speed cameras are sometimes defective or that the fines are too high. Some opponents of speed cameras actually claim either that the cameras do not alter driver behaviour or that speed itself is not a key element in causing road accidents and increasing their severity. The last claim, that speed is not a significant factor in road accidents is a very dangerous one as a large number of reputable studies have demonstrated the direct opposite.
It is obviously easy for some motorists to tell themselves they are sufficiently skilled or know the road well enough to be able to speed without risk. However, studies from around the world have demonstrated that this is not so. Although speed may not be the sole contributory factor to accident causation, it is a major one. Further, when an accident occurs, the more rapidly a vehicle is travelling the greater the damage inflicted on those within it.
Therefore, the prevailing tendency within some sections of the Australian media to focus on the supposed faults of the nation's speed camera network could have the unfortunate consequence of encouraging motorists to believe both that they have a right to speed and that they can do so in safety.
