Simulation Based-MCDM Approach for Evaluating Traffic Solutions

Abstract

Traffic congestion problems have dramatically esca-lated with the increasing volume of vehicles, pedestrians, and cyclists in the face of limited road capacity. This re-search aims to reduce the time road users spend in the system (school-zone area) and improve the efficiency of the process of dropping off and collecting children from a crowded school area. The study integrates discrete-event simulation (DES) and multi-criterion decision-mak-ing (MCDM) techniques to comprehensively evaluate the proposed alternatives to select an optimal solution based on many performance measures. A real-world case study of the traffic and congestion problems experienced by parents when they drop off and fetch their children from school during peak hours is presented. A heuristic algorithm was developed to simulate the random and un-predictable behaviour of road users. A cost-benefit anal-ysis considered the impact of waiting time, traffic den-sity, number of accidents, additional fuel expenses, and emission reduction. The technique for order of preference by similarity to ideal solution (TOPSIS) and preference selection index (PSI) methods were utilised to select the most appropriate option for parents. The study found that the integration of simulation techniques with MCDM methods could efficiently solve traffic problems.

Optimizing Sugar Manufacturing: A Hybrid Simulation-Based Approach and MCDM for Efficient Decision Making

“…Traffic congestion is common in society and occurs when more vehicles are on a road than it can handle. Numerous studies have addressed this issue and proposed various solutions [7]. Modern simulation tools are often the most essential tool in analyzing traffic Similarly, one to two DLU stations are operational throughout all three shifts.…”

Highlighting Traffic Accidents on Roundabouts Using MRSS-AHP Expert System

“…Thus, it is urgent to investigate the traffic accidents at roundabouts in urban areas to improve the roundabouts' designs and operations to maintain their effectiveness. Traffic safety is a complex issue that requires a comprehensive evaluation of accident causes to establish an optimal combination of appropriate measures to save lives and reduce social and economic costs [3,4]. Moreover, there is a need to evaluate and analyze aspects with varying importance levels using different processing methods.…”
