Comparative Risk Analysis of Using the Markings for Ground and Raised Pedestrian Crossings

Abstract

The quality of road construction and ensuring road safety is one of the most important tasks today. One of the tools for solving this problem is risk-oriented approach. For the first time, the authors presented a comparative analysis of using the markings for ground and raised pedestrian crossings, taking into account the permissible risk of a breakdown of the car’s chassis and the value of the permissible risk of deterioration in the conditions of the driver and passengers when the car is moving along the indicated crossings with permissible speeds. From the results obtained above it follows that the use of the ground pedestrian crossing with an average marking line height of 6.0 mm, a weighted average marking line length from 4.0 m to 6.0 m, and a car speed at the crossing of 60 km/h (as regulated by road traffic code in the city limit) is considered permissible. The risk of breakdown of the car’s chassis at the speeds indicated in Russian State Standard GOST R 52605-2006 may remain acceptable (1 × 10−3) if the weighted average length of the raised pedestrian crossing also increases. Such pedestrian crossings are acceptable, for example, in large metropolitan areas.
