In the work we performed a review of studies of foreign scholars on changing the reaction time of the driver depending on various road conditions, namely the change in the response time when using the traffic light regulation. Earlier by the authors of this article have already been carried out research in the field of throughput of a site of a highway with traffic regulation, which showed that this value depends on the time of reaction of the driver. In this article the estimation of how much bandwidth the highway using different result obtained in the course of analysis, time value of reaction of the driver and is a direct correlation bandwidth from the time of reaction of the driver. The values obtained allow to conclude that taking into account the psycho-physiological characteristics of drivers (response time) will have a significant impact on the throughput and the various methods of organization and reorganization of sections of the road network, implementation of which is used investigated the amount of bandwidth.

В работе выполнен обзор исследований зарубежных ученых по изменению времени реакции водителя в зависимости от различных дорожных условий, а именно изменение времени реакции при использовании светофорного регулирования. Ранее авторами данной статьи уже были проведены исследования в области пропускной способности участка автотрассы при светофорном регулировании, которые показали, что данная величина зависит от времени реакции водителя. В данной статье проведен расчет величины пропускной способности автотрассы при использовании различных, полученных в ходе анализа, значений времени реакции водителя и установлена прямая зависимость пропускной способности от времени реакции водителя. Полученные значения, позволяют сделать вывод о том, что учет психофизиологических характеристик водителей (время реакции) будет оказывать значительное влияние на пропускную способность и различные методы организации и реорганизации участков улично-дорожной сети, при реализации которых используется исследуемая величина пропускной способности.

The scope of this paper is to analyze performance of automatic vehicles during data dissemination with the realtime updated road information into the maps followed by the vehicle moments. Both modeling and development of the additional subsystems needed such as communications, reference/sensor systems and mobility are considered. The primary reason is that for solving both traffic congestion and safety problems to save time and fuel. The proposed location based algorithm analyses the features of complete automation of the driving function with suitably equipped road facilities.

In this paper, we consider a regulation problem of an urban transportation network. From a given timetable, we aim to find a new schedule of multiple vehicles after the detection of a disturbance at a given time. The main objective is to find a solution maximizing the level of service for all passengers. This problem was intensively studied with evolutionary approaches and multi-agent techniques, but without identifying its type before. In this paper, we formulate the problem as a classical one in the case of an unlimited vehicle capacity. In the case of a limited capacity and an integrity constraint, the problem becomes difficult to solve. Then, a new coding and well-adapted operators are proposed for such a problem and integrated in a new evolutionary approach.
