Modeling the potential accidents at the guarded railroad crossing line Surabaya–Lamongan

Abstract

Traffic safety at railroad crossings considered poorly understood by the road users. A good safety understanding at railroad crossings is necessary to prevent potential accidents. This condition is possibly achieved if factors causing the accidents are clearly known. This study aims to find out factors with potentially causing accidents in a railroad crossing, especially related to traffic volume, vehicle queue length, past year accidents, and land use around the railroad crossing. Data were collected from the data inventory survey, which was then analyzed using regression analysis. The results found three equations types based on the land use, respectively as: Type 1 (Railroad Crossing-Local Road/Collector) Y = 0,97 + 2,89x1 + 0,042x2; Type 2 (Railroad Crossing-Public Facilities) Y = 0,693 + 4,4x1 + 0,006x2; Type 3 (Railroad Crossing-Approaching Intersection) Y = -0,209 + 3,140x1 + 0,018x2. This study was benefited to design the policy as well as the layout of railroad crossings in order to minimize the potential accidents in the railroad crossing areas.
