The Project of Organizing Non-Stop Traffic at T-Intersections (Tyumen Case Study)

Abstract

The constant growth in the number of cars and trucks in single industry towns is forcing road design engineers to find ways convenient for all road users and pedestrians to move at intersections. Fulfilling such conditions is a difficult task but it can be solved, especially if there are many T-shaped intersections along the entire length of the road. Most often they are located along the line of railways, heating mains, river or lake banks, parks, etc. Since there are no adjacent roads, it is possible to ensure continuous movement of cars, but only in one direction.

The objective of this work is to substantiate the project aimed at ensuring unhindered traffic at T-intersections of vehicles following 50 let VLKSM street in the city of Tyumen.

To achieve this objective, the method of observation and recording, as well as the analysis of operation of optical devices that regulate passage of cars at intersections were used. With newly designed travel mode, there is no infringement of rights in relation to other motorists and pedestrians since the traffic light mode for the rest of segments keeps the same counting in seconds. A system of safe pedestrian crossing is envisaged along with an improvement in the environmental component of the whole city.

For initial adaptation of motorists to new conditions, it is proposed to use a side green vertical arrow attached to the traffic light and signal columns that delimit traffic lanes for a «slow merge» into the flow of those leaving the secondary road. An undeniable advantage of this type of design is the minimum cost of reconstruction of intersections. Based on author’s own observations, it can be argued that this project increases traffic of vehicles moving from the central part of the city to the eastern part by 1,5–1,8 times.
