Assessment of the Conditions for Allocating Independent Road Safety ITS Subsystem

Abstract

Intelligent transport systems (ITS) are developing dynamically in many countries around the world, including Russia. One of the main stated goals is to improve road safety (RS). The paper considers the prospects and conditions for the allocation of an independent RS subsystem within the framework of an intelligent transport system. A structural model is obtained that is easy to implement in the existing ITS. The transition from the closed type of ITS functioning is proposed: for the successful functioning of the RS subsystem, the use of dispatching information, forces and means of state services is additionally recommended. The results of evaluation of the ability to use the accessible tool of ITS components in the proposed subsystem that preliminarily grouped in two blocks: block “monitoring” and block “management”. The study was conducted using the example of the Russian Federal road A-322. Based on the use of the risk theory and “Driver-Car–Road–Environment” approach to assessing the level of potential danger, an algorithm for the functioning of a complex RS subsystem has been developed, the main idea of which is to compare the current risk to the established limit value. A multiplicative form is proposed as a basic model for assessing the risk of road traffic accident. Based on the results of the study, recommendations were made on the conditions and opportunities for implementing the RS subsystem.
