Brief Analysis on the Control and Management Measures of Urban Road Congestion

Abstract

With the rapid development of cities, traffic congestion appears more or less in large and small cities. With the continuous increase of motor vehicles, problems such as traffic congestion, energy shortage and environmental pollution have also appeared one after another. Urban traffic problems are getting worse, and urban congestion needs to be solved urgently. This article focuses on the optimization of urban land layout, expansion of urban transportation infrastructure construction, strict control of the total number of vehicles, priority development of public transportation, and vigorous development of intelligent transportation systems. Countermeasures and solutions are proposed in this paper to alleviate traffic congestion and to make effective suggestions.

Potential of Connected Fully Autonomous Vehicles in Reducing Congestion and Associated Carbon Emissions

“…Researchers have over the years published different definitions of traffic congestion, with the most common being defined as a traffic state impacted by traffic flow parameters-such as volume, speed, and density-or as a phenomenon of lost time caused by slow moving vehicles. Another theory looks at the relationship between traffic supply and demand, where traffic congestion develops when the traffic demand exceeds the amount of traffic that the road can supply (capacity) [19]. The term 'congestion' is therefore defined in the context of this research as the state of traffic impacted by lost time (delay) caused by slow-moving vehicles.…”

“…Jiehao Sun et al (2021) analysed the control and management of urban traffic congestion, proposing countermeasures and solutions to alleviate traffic congestion by breaking down six specific ways in which urban congestion could be optimised. These are listed in Table 1 [19]. Their research argues that one way to optimise conditions to reduce congestion is "vigorously" developing intelligent transportation systems to make use of and improve the existing road resources.…”
