Evaluating the impact of intersections on traffic using computer software

Abstract

Traffic intersections are considered essential elements in any traffic system, playing a vital role in organizing traffic flow and directing vehicles. The importance of these intersections lies in being the points where different roads intersect, facilitating movement between areas. However, poorly designed intersections can lead to significant issues, such as congestion and long wait times, negatively impacting drivers' experiences and the effectiveness of the traffic system. When intersections are not well-designed, they result in irregular traffic flow, necessitating the need for precise scientific studies to analyze traffic flow. These studies should rely on sound scientific principles to understand the relationship between intersection design and traffic performance. There can be cost-effective operational solutions, such as optimizing traffic signals or changing movement patterns, which contribute to improving efficiency. A review of previous studies shows an increasing interest in evaluating the impact of intersections on traffic using computer programs. This study aims to review the most important of these studies and focus on key points that highlight how to improve the performance of these intersections and increase the efficiency of the traffic network. This paper discusses some studies related to intersections and their effects on traffic, with a focus on using computer programs to assess their performance. These studies include traffic performance analysis and examining how intersection design and traffic signals affect movement efficiency. Programs such as "Synchro," "VISSIM," "SIDRA," and "HCS" are used to evaluate the level of service and delay times at various intersections. Simulation techniques are also employed to solve traffic problems and improve flow, with some studies comparing these programs to determine their different impacts on traffic.
