Tackling Accident Blackspots Head On
In South Australia, a blackspot is considered to be somewhere with at least three casualty crashes reported in five years; similar criteria are used in other developed jurisdictions. Such a small number of crashes is inherently highly variable, [...]
Using Microsimulation To Evaluate Traffic Safety
As the use of traffic models in a planning context steadily grows, the need has arisen to be able to evaluate traffic safety based on microsimulations, thus allowing for an ex-ante evaluation of the effects of certain traffic management measures [...]
A framework for evaluating safer routes to schools
Do small scale engineering measures make a real difference to parent’s perceptions of safety on the school run? This paper reports on how Brighton and Hove Council has developed an evaluation framework for their Safer Routes to School programme [...]
Accidents at blackspots: estimating the effectiveness of remedial treatment, with special reference to the 'regression-to-mean' effect
This paper looks at the estimation of the effectiveness of remidial treatment for accident blackspots with special consideration of the 'regression to mean' effect [...]
Speed cameras - their true effect on driver behavior
This paper, based on MSc project which measured the speeds of large samples of drivers around four contrasting camera sites. The aim was to determine the 'sphere of influence' of the camera sites [...]
Applying systems methodology to the road safety challenge
In 1999, the estimation of fatalities in road crashes worldwide was 800,000 per year, forecast to grow to between 1.1 and 1.2 million in 2010 and to between 1.3 and 1.4 million by the year 2020 (Silcock, 2003). Specific time-proven strategies [...]
Subjective and objective evaluation of risk on roadway curves
This paper considers the level of risk, via a subjective and objective evaluation, of risk on roadway curves. It considers drivers' own perception of risk from a study at a section of a road in Athens, Greece [...]
Accident blackspots and the bivariate negative binomial
This paper shows how the method of maximum likelihood in connection with a bivariate negative binormal distribution may be used to seperate treatment effects from regression to the mean effects when analysing data giving the frequency of accidents [...]
A trial in Norfolk of interactive speed limit signs
A major contributory factor in road traffic accidents is excessive speed. Automatic speed warning signs, which are triggered when drivers exceed preset threshold speeds, might make drivers more aware of their own excess speed and the speed limit on [...]
Safety on the M42 Active Traffic Management Project
In September 2006, the M42 Active Traffic Management pilot introduced controlled use of the hard shoulder to the UK motorway for the first time. Press articles at the time focussed heavily on the question of safety. In reality, this innovation [...]
