Overtaking Prohibition Safety Effects on Two Lane Rural Roads
This paper presents the results of a cost-effectiveness study concerning the effects of an overtaking prohibition on two lane rural roads. Overtaking prohibitions are being implemented in the Netherlands aiming to improve safety. Overtaking frequency on road sections with and without overtaking prohibition are measured by means of camera observations Overtaking frequencies were determined by co...

متن کاملEstimation Model of Two-Lane Rural Roads Safety Index According to Characteristics of the Road and Drivers’ Behavior
Vehicle crashes are amongst the major causes of mortality and results in losses of lives and properties. A large number of the vehicle crashes occur on rural roads. Accidents become more noteworthy in two-lane roads due to going and coming traffic. Therefore, prediction of crashes and their causes are considerably important to reduce the number and severity of the accidents. The safety index is...

Transportation Research Record: Journal of the Transportation Research Board, No. 2223, Transportation Research Board of the National Academies, Washington, D.C., 2011, pp. 9–17. DOI: 10.3141/2223-02 Operating speed is most frequently represented by the 85th percentile speed (V85) of vehicles passing at a given road location, in a nonplatoon condition, and it is usually determined by spot speed...
متن کاملIntegrated American-European protocol for safety interventions on existing two-lane rural roads
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...
