A Comprehensive Review on Traffic Control Modeling for Obtaining Sustainable Objectives in a Freeway Traffic Environment

Abstract

Traffic control strategy plays a significant role in obtaining sustainable objectives because it not only improves traffic mobility but also enhances traffic management systems. It has been developed and applied by the research community in recent years and still offers various challenges and issues that may require the attention of researchers and engineers. Recent technological developments toward connected and automated vehicles are beneficial for improving traffic safety and achieving sustainable goals. There is a need to develop a survey on traffic control techniques, which could provide the recent developments in the traffic control strategy and could be useful in obtaining sustainable goals. This survey presents a comprehensive investigation of traffic control techniques by carefully reviewing existing methods from a new perspective and reviews various traffic control strategies that play an important role in achieving sustainable objectives. First, we present traffic control modeling techniques that provide a robust solution to obtain reasonable traffic and sustainable mobilities. These techniques could be helpful for enhancing the traffic flow in a freeway traffic environment. Then, we discuss traffic control strategies that could be helpful for researchers and practitioners to design a robust freeway traffic controller. Second, we present a comprehensive review of recent state-of-the-art methods on the vehicle design control strategy, which is followed by the traffic control design strategy. They aim to reduce traffic emissions and energy consumption by a vehicle. Finally, we present the open research challenges and outline some recommendations which could be beneficial for obtaining sustainable goals in traffic systems and help researchers understand various technical aspects in the deployment of traffic control systems.

Controlling Traffic Congestion in a Residential Area via GLOSA Development

“…The city suffers from high levels of pollution due to population growth over the past years, with a population of 9 million people. By focusing on traffic routing conditions, for example, eco-driving and eco-routing, governments seek to reduce the generation of pollutants and energy use by reducing traffic congestion and improving other factors [22]. Therefore, there has been a need to conduct more relevant research to improve the level of air quality.…”

Towards efficient urban road transport using multimodal traffic management

“…Urban traffic management aims to maintain and improve safety and efficiency in the traffic network by guiding travelers in case of disruptions or incidents to reduce congestion. Reducing congestion and improving the efficiency of the transportation network also reduces traffic emissions (Sheikh and Peng, 2022). There are traffic management measures affecting both the supply and the demand of traffic, as illustrated in Figure 2.1.…”

Inferring Traffic Patterns of Dhaka City: A Spatio-temporal Analysis over a Year

“…This analysis research also provides valuable insights that help communities optimize infrastructure, alleviate traffic congestion, and improve overall road safety by methodically evaluating the patterns and dynamics of vehicular movement Neilson et al (2019). Recently, traffic volume has been increasing every year in almost every mega city which further causes traffic congestion due to over-supplied traffic on limited roadways Sheikh and Peng (2022). As a result, the significance of traffic pattern analysis research is gaining attraction Kulshrestha and Kulshrestha (2022).…”
