“…When choosing the cycle length, we have to bear in mind that a cycle which is too short lowers the junction capacity and vice versa, where a cycle which is too long might lead to the situation where the green phases during which no vehicle is passing through the junction are not utilized. The long cycles also increase time losses and lead to a decrease in effective LSD-based junction control [35]. The cycle length ranges from 40 to 120 s and depends on the number of vehicles entering the junction, the way of branching out and its intensity, the passage width and length, and junction construction work [22].…”

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.

Over the past few decades, the increasing number of vehicles and imperfect road traffic management have been sources of congestion in cities and reasons for deteriorating health of its inhabitants. With the help of computer simulations, transport engineers optimise and improve the capacity of city streets. However, with an enormous number of possible simulation types, it is difficult to grasp valuable, innovative solutions which are of the greatest value to city citizens. In this work, the authors expose various problems within this area having reviewed and analysed over 130 papers selected out of 1200 works in the field of urban simulations. The study describes the selection process of important papers and highlights characteristics of microsimulations, macrosimulations, computation optimisations and other approaches found in the literature which are especially useful and should be further built on in the future. They present and compare results provided in reviewed works in terms of throughput improvement, queue, waiting and travel time reduction, vehicle speed increase, speed‐ups as well as assumed simulation parameters. Finally, they focus on research gaps, such as a small number of works considering crisis simulations, few real‐world scale simulations as well as on software architectural changes and low‐level optimizations.

“…Traffic lights at downstream intersections should increase the proportion of release phase time, including left and right turns, to accelerate the evacuation of stranded vehicles. After the traffic order of the road section is restored, the traffic lights at the upstream and downstream intersections are restored, and the traffic in the whole road section is restored [24], [25]. The rest of the flow reduction measures are also withdrawn, including that the lane traffic lights are turned green and the temporary signboards at the upper intersections are removed; in addition, the electronic information screen and the radio stations should all report that the traffic is smooth again so that the vehicles do not make unnecessary trips that may increase the traffic pressure on the surrounding roads [26].…”

In order to reduce the fluctuations of traffic flow and the impacts of traffic flow fluctuations, thereby increasing the level of service of roads and constructing the Internet of Things-based traffic system, based on the various causes of traffic flow fluctuations, the countermeasures were taken, such as the optimization of lanes, the management of intersections, the improvement and perfection of slow-vehicle lanes and bus stops, the timely renewal of traffic signs and marks, the rational arrangements of road operations, and the removal of visual obstacles, etc. The research results showed that these countermeasures could effectively reduce the hidden peril of accidents and improve the road capacity, thereby improving the level of service of roads, which provided a theoretical foundation and basis for road engineering design and traffic management. It can be seen that improving urban traffic through rational management and control measures can effectively improve the level of service of urban traffic. INDEX TERMS Urban road, traffic flow fluctuation, level of service, countermeasure.
