Speed management RoadSafe believes that eliminating excessive speed will

save lives.


The challenge is for driving at inappropriate speed to be seen as anti



Road Safe works with others... To support and promote programmes of


coordinated action in a whole range of areas including engineering, technology,


training, communication, regulation and its enforcement. To develop integrated


initiatives to encourage stakeholders to introduce sensible speed policies and


modern technologies to give better driver information. To identify and promote


local successful speed reduction initiatives and policies, then campaign to have


them adopted nationally. Download Road Safe's policy on speeding Research


from the Transport Research Laboratory TRL has provided evidence of three


different types on the effect of speed on crashes and collisions. Studies of


individual drivers show that when exceeding the average speed by 25% a driver


is about 6 times as likely to be involved in an incident in comparison with a


driver adopting the average speed. This is similar to the risk associated with


alcohol at the legal limit of 80mg/100ml blood alcohol content. Studies of road


sections show that for roads of each type, the number of crashes and collisions


Increases with increasing average speed  the effect varies on different road


types and is strongest for the slowest roads. A ball-park figure is that each


1mph reduction in average speed is accompanied by a 5% reduction in


accidents. Traffic calming measures (e.g. road humps and chicanes) in 20mph


zones have reduced average speeds by about 10mph and resulted in a 50%


reduction in collisions. Measures adopted in rural villages have reduced


average speeds by about 5mph and resulted in at least 20% fewer collisions.


Research at Napier University shows that individuals are aware that speeds


they normally adopt when alone are actually unsafe. For example, participants


described situations in which they would slow down such as the presence of a


speed camera or child in the car. This suggests that individuals know that if they


see a camera they would need to slow down because they would be exceeding


the limit. Changing attitudes to speed need to relate to influences on speed:


Obligations - such as keeping appointments, picking up kids, and generally


meeting the tight time schedules of modern life. Opportunities - that allows


speeding to take place, such as a fast car and a clear road. Inclinations -


performing behaviours in accordance with personal preference such as I like to


speed as it feels good. Road safety professionals recognise that speed


management is a very important tool for improving road safety. However,


improving compliance with speed limits and reducing unsafe driving speeds are


not easy tasks. Many drivers do not recognize the risks involved and often the


perceived benefits of speeding outweigh the perceived problems that can result.


An excellent international manual consisting of a series of 'how to' modules is


now available. It provides evidence of why speed management is important and


takes the user through the steps needed to assess the situation in their own


country. It then explains the steps needed to design, plan and implement a


programme, including how to obtain funding, set up a working group, develop


an action plan and, if necessary, introduce appropriate legislation. It considers


the potential role of measures involving engineering and enforcement, as well


as using education to change speed related behaviour. Finally, the manual


guides the user on how to monitor and evaluate the programme so that the


results can be fed back into programme design. For each of these activities, the


document outlines in a practical way the various steps that need to be taken.
