Traffic Signal Controller Optimization Through VISSIM to Minimize Traffic Congestion, CO and NOx Emissions, and Fuel Consumption

Abstract

In developing countries with heterogeneous traffic, such as Sri Lanka, it is possible to observe severe traffic congestion at intersections and traffic corridors. The main objective of this study was to demonstrate the optimization of traffic signal controllers using VISSIM microsimulation software. It aimed to minimize traffic congestion, emissions, and fuel consumption. This study focused on developing a traffic signal controller optimization program for a congested traffic corridor which consisted of a three-legged signalized intersection, a four-legged unsignalized intersection, and a three-legged unsignalized intersection. The entire corridor was modeled here, and the already signalized three-legged intersection was optimized. Traffic signal controller optimization was done separately through the built-in optimization features in VISSIM and Webster’s Method. The results showed that emissions and fuel consumption were reduced by 14.89 % in VISSIM optimization and 14.11% in optimization using Webster’s Method. Through the comparison between the VISSIM optimized signal timing and manually calculated signal timing, it was found that the signal timing optimization provides much more improved results than the manual signal timing calculations. Using the proposed methodology, the traffic signal controllers can be optimized within a short duration in very few steps without any iterations compared to the existing traffic signal controller optimization techniques. Therefore, the proposed methodology is a good alternative method to optimize the traffic signal controllers.

“…The average number of vehicles observed was approximately 43,792. At Intersection J2, the highest number of vehicles was recorded on 24 August 2023, at 34,564, while the lowest was on 25 January 2023, at 28,308 The average number of vehicles observed was approximately 31,292. At Intersection J3 the highest number of vehicles was recorded on 28 December 2023, at 58,098, while the lowest was on 26 January 2023, at 39,067.…”

“…Due to the diverse results of the previous stage of analysis, the microsimulation in PTV Vissim [26][27][28] will be based on the example of Intersection J3. The model includes three variants: with maximum intensity as indicated in the previous stage of analysis, minimum vehicle intensity, and average intensity from the entire study period.…”

“…According to [11]. the VISSIM microsimulation software is the most well-known and often used of those.…”

“…From Mother Theresa intersection to Sarvanton intersection, travel time and delay were reduced after signal synchronization by 102.4 seconds and 110.32 seconds, respectively. The traffic signal controllers have been optimized for a congested corridor in Malabe town, Sri Lanka using Vissim software [11]. They found that emissions and fuel consumption were reduced by 14.89%.…”

“…Intersection saturation flow and intersection capacity are important parameters in planning and regulating traffic at highway intersections. Knowledge of intersection saturation flow is needed to calculate intersection capacity and plan efficient traffic management [6]. Traffic intersections, as road nodes, are also a major concern because they often cause conflicts between traffic participants [7].…”
