A RESEARCH ON ANALYSIS OF JUNCTION DESIGN-APPLICATION ERRORS

Abstract

It is a known fact that the majority of traffic accidents in our country and other countries are at the crossroads. Accidents occurring at intersections are mainly due to driver errors and lack of infrastructure. It is of particular importance to design these areas where many vehicles and pedestrians come from different directions and are divided into other directions, and to implement the intersection projects that are designed. This makes it necessary and compulsory to perform intersection designs and applications by experts of the subject. Otherwise, intersections that are wrongly or incompletely designed and implemented force drivers to make mistakes and this causes accidents. The diversity of accidents occurring at intersections deals with intersection design and application errors. For this reason, it is important to detect and analyze the accidents that have occurred in the last few years in the examination of the existing intersections. Capacity problem is an important factor in the design and implementation of the level (level) intersections and multi-level (bridge) intersections named according to the number of branches, marking or islands and traffic control system. It has been determined by me that all signalized intersections and signaling programs are the same in one of our provinces. This reveals that capacity is not considered in intersection design. In a junction, the more important it is for all passes to be carried out safely and safely, the more important it is to pass the maximum vehicle over that unit time in that junction. In this context, the safety and security and other factors (capacity, vehicle numbers and signal markings, pedestrian crossings, geometric analysis, etc.), which are chosen randomly in the study in Diyarbakır, Bağlar district, intersection of the new state intersection (Çevlik street and Yeni hal street). The current situation will be evaluated. As a result of these determinations and evaluations, it will be ensured to reach design and application errors. As a result of the study; Solutions in which existing errors are corrected will be presented.
