MULTIVARIATE ANALYSIS OF MOTORCYCLE ACCIDENTS AND THE EFFECTS OF EXCLUSIVE MOTORCYCLE LANES IN MALAYSIA

This paper presents a multivariate analysis on the impact of the exclusive motorcycle lane on motorcycle accidents along the Federal Highway Route 2, Malaysia. A number of statistical models have been developed to explain the relationship of motorcycle accidents and explanatory variables relevant to motorcycle safety. The best model showed that motorcycle accidents are directly proportional to the cubic power of traffic flow and reduced by approximately 39% with the motorcycle lane. A clear benefit of this lane is observed when the traffic flow exceeds 15,000 vehicles per day per lane for motorcycle proportion of between 20% and 30%. Besides supporting the notion for motorcycle segregation, this finding provides an initial guideline on the warrants for an exclusive motorcycle lane for highly motorcycled countries in Asia.

Development of Realistic Safety Target and Strategic Safety Programmes in Malaysia

This paper presents the approach taken by the Malaysian Government in setting up a more realistic safety target in Malaysia. The target was based on a time series multiplicative model and the main traffic exposures used were population, vehicle, road length and change in recording system. Based on this model, a 30% reduction target was established to offset the “do minimum” approach currently adopted in the country. Recent experiences on the motorcycle safety programmes are presented and the new motorcycle safety initiatives are discussed.
