This paper summarises findings on the road safety performance and bus incidents in Melbourne along roads where bus priority measures had been applied. Results from an Empirical Bayes safety evaluation showed a 14% reduction in accidents (significant at 90% level). An empirical analysis of the incident types revealed significant changes in the proportion of incidents involving buses hitting stat...

safety analysis of the roads through the accident rates which is one of the widely used tools has been resulted from the direct exposure method which is based on the ratio of the vehicle-kilometers traveled and vehicle-travel time. however, due to some fundamental flaws in its theories and difficulties in gaining access to the data required such as traffic volume, distance and duration of the t...

This paper aims at improving two main uncertain factors in neural networks training in developing a composite road safety performance indicator. These factors are the initial value of network weights and the iteration time. More specially, rough sets theory is applied for rule induction and feature selection in decision situations, and the concepts of reduct and core are utilized to generate de...

Abstract: Background and aims: Performance assessment and also performance indicators have a great importance in all aspects of life. By these indicators appropriate responses to what is happening for make some improvement, could be determined. In the past, the safety and health performance of organizations was measured with using of some indicators from the USA Occupational Health and Safet...

Road traffic accidents account for approximately 3000 deaths on a daily basis, and 50 million injuries and 1.2 million deaths each year. In low-income and middle income countries, road traffic accidents account for 85% of deaths and 90% of annual disability. Casualties of this magnitude are a serious problem throughout the world and create a significant impact on society. In addition, neurologi...

Purpose The main purpose was to integrate two strategies for road safety analyses (qualitative: audits, inspections; and quantitative: accident predictions) and develop a possible protocol for the safety interventions on existing two-lane rural road segments. Those road sections do not typically belong to the TEN-network, to which the 2008/96/EC Directive is mainly oriented. Hence, they could l...

Work zone safety studies have traditionally relied on historical crash records—an approach which is reactive in nature as it requires crashes to accumulate first before taking any preventive actions. However, detailed and accurate data on work zone crashes are often not available, as is the case for Australian road work zones. The lack of reliable safety records and the reactive nature of the c...
