RESEARCH OF TRAFFIC CHARACTERISTICS AND DETERMINATION OF LOAD COEFFICIENTS OF MAIN STREETS OF THE CITY OF LUTSK

Abstract

Modern highways must provide the possibility of safe and high-speed movement of vehicles, which is possible only with high transport and operational condition of roads and streets, characterized by speed, cost of transportation, safety and ease of travel, capacity and congestion.

The main characteristics of road traffic are the intensity and speed of traffic, the composition and density of traffic, the level of traffic comfort.

The composition of the traffic flow is determined by the relative number of vehicles of different types (cars, light, medium and heavy trucks, buses, road trains and trolleybuses, etc.).

Speed, which characterizes the target function of traffic, is one of its main indicators.

The density of traffic determines the degree of traffic saturation. It is estimated by the number of vehicles that are on one kilometer of one lane.

The level of traffic comfort is a complex indicator of economy, safety and comfort of road traffic. The main characteristics of the level of traffic comfort: the load factor of the road, the speed factor and the traffic saturation factor.

This article presents the results of research on the intensity of traffic of different vehicles on the main streets of Lutsk and the load factors of these streets, presents proposals for the redistribution of traffic flows.
