Abstract
The increasing of traffic sign and/or light violations is a commonly views in many countries. Even it was occurred intentionally which indicates that drivers accept its possible consequences. The constant fatality index of motorcyclist strongly indicates that determinant variables behind their risky behaviour and/or accident involvement should be further investigated and managed systematically. Accordingly, this paper focuses on motorcyclist accident risk management, particularly at un-signalized segment, by combining the aggregated-individual and expert expectancy approaches. Therefore a questionnaire and braking manoeuver test were undertaken at closed circuit course. The result shows that speeding behaviour was caused by trip purpose and triggered by perception about their braking and hazard detection abilities. In addition, only 24 % of 56 % of riders who believed that their braking capability was above average could apply high braking capability so that most riders might involve in crash due to the average critical crossing gap choice at the monitored intersection. This explains that their speed choice should be deal with their braking capability. However, the overlay policy at the monitored intersection indicates that the unbalanced between mobility and safety still to be a latent issue, which virtually could be bridged by using a standardized braking capability.
Highlights
A steady increase in traffic accident number and/or fatalities over the last 20 years triggered the United Nation’s Decade of Action (DoA) on Road Safety 2011– 2020
It is thought that the high number of accident and the constant fatality index over the years is worth to be considered to be a disaster in transportation field so that a synchronized accident risk management strategy should be developed continuously, at risky road segment areas such as un-signalized intersection, crossing lane, etc
This paper focuses on how to develop an appropriate accident risk management strategy suited to driver expectancy and road safety services, because the unbalanced in safety performance and mobility needs was a latent issue that should be bridge
Summary
A steady increase in traffic accident number and/or fatalities over the last 20 years triggered the United Nation’s Decade of Action (DoA) on Road Safety 2011– 2020. It is thought that the high number of accident and the constant fatality index over the years is worth to be considered to be a disaster in transportation field so that a synchronized accident risk management strategy should be developed continuously, at risky road segment areas such as un-signalized intersection, crossing lane, etc. Intersection areas are commonly known to be one of the most vulnerable traffic accident segments due to insufficient braking capability [3], poor sight distance [4], traffic sign violations [5], speeding in the dilemma zone [6], etc. A number of accident at intersection occurred due to insufficient braking capability and/or inappropriate speed choices [3], when the distance of crossing vehicle intended for entering or exiting a minor road (critical crossing gap acceptance) is too close with the major stream vehicle
