Currently, there are quite a lot of incorrect procedures and mistakes that occur in the forensic area, which lacks analytical approaches toward solving the causes of accidents using s–t diagrams (distance–time diagrams) combined with the software simulation applications. When analyzing accidents, the correct information is of key importance. The aim of this article is to define a new specific technical and analytical approach toward handling expert’s reports on traffic accidents in road transport at intersections, with respect to the traffic lights. A simulation program application is used as a progressive means of accident evaluation. This procedure must become a standard in the methods of modern traffic accident analysis. The application of this methodology with simulation tools for accident reconstruction enables one to perform a very precise analysis of traffic accidents. Mutual space and time relationships of vehicles’ movements have been evaluated here, depending upon the intersection signal plan. To demonstrate the methodology, a real case is used here, reconstructed by means of the complex analytical simulation software PC-Crash. A procedure processed by these means can be beneficial for forensic traffic accident analysis.

“…The main problem is the frequent traffic congestions in many major cities in the world [1]. The constant-time traffic-control method is not optimal in regulating traffic, and the current densities of vehicles passing during peak hours may result in unavoidable congestions [2]. The increasing volume of vehicles is not comparable to the number of roads available [3]; this results in the buildup of vehicles on certain roads during peak hours, which causes congestions on the roads.…”

This problem interferes with drivers and affects the local economy [2]. The impacts it may have on cost and time effectiveness may take the form of increased fuel consumption, traffic emissions, and noise.…”

<span lang="EN-US">Traffic jam that is resulted from the buildup of vehicles on the road has become an important problem, which leads to an interference with drivers. The impacts it has on cost and time effectiveness may take the form of increased fuel consumption, traffic emissions, and noise. This paper offers a solution by creating a smart traffic light using a fuzzy-logic-based microcontroller for a greater adaptability of the traffic light to the dynamics of the vehicles that are to cross the intersection. The ATMega2560 microcontroller-based smart traffic light is designed to create a breakthrough in the breakdown of congestions at road junctions, thereby optimizing the real-time happenings in the road. Ultrasonic, infrared, and light sensors are used in this smart traffic light, resulting in the smart traffic light’s effectiveness in parsing jams. The four sets of sensors that are placed in four sections determine the traffic light timing process. When the length of vehicle queue reaches the sensor, a signal is sent as the microcontroller’s digital input. Ultrasonic and infrared sensors can reduce congestions at traffic lights by giving a green light time when one or all of the sensors are active so that the vehicle congestions can be relieved.</span>

“…Minimizing the stop numbers and delays is an important step to solve this problem at signalized intersections [4]. The minimization of delays and stops at signalized intersections can be achieved in two different ways: with most proper designing of intersection geometry (geometric and topographic arrangements) and with determining of signal timings considering traffic demands at intersection approaches (operational arrangement) [5][6][7][8]. Hence, effective signal management is a quite important factor to reduce the delay, fuel consumption, noise pollution and exhaust emissions and to increase the intersection capacity and level of service of intersection [9][10][11][12].…”

The effectiveness of fixed-time management systems dramatically decreases in case of fluctuated traffic demands at signalized intersection approaches. This leads to the waste of time in traffic and may cause material, psychological and ecological problems. Especially in recent years, to minimize the negative impacts of these problems, many researchers focus on Intelligent Transportation Systems (ITS). As it is known, one of the Intelligent Transportation Systems applications is called vehicle-actuated (traffic-actuated) management systems.Because the success of these types of applications is directly related to the created control logic, the selection of the most proper control parameters for the created control logic is an important issue. This study aims to create an effective control logic and flow chart for the vehicle-actuated management system. At the end of the analyses, it is seen that the created vehicle-actuated management system can adapt to fluctuations in traffic demands at signalized intersection approaches. Average vehicle delays, fuel consumptions and exhaust emissions can be reduced significantly by the created system. Especially, in case of fluctuations in traffic demands at 2 intersection approaches exist, it is concluded that the performance of the intersection can increase enormously with the created vehicle-actuated management system.
