Book excerpt: Urban traffic congestion is a significant issue that costs hundreds of billions of dollars annually in the United States alone from delay, fuel consumption, and environmental impacts (Schrank et al., 2105). Transportation engineers have tried to combat this congestion in a variety of ways, one of the most inexpensive methods being traffic control. Various attempts have been made to quantify how traffic control impacts the performance of urban transportation networks. A recent study examined the impacts of street directionalityspecifically, the use of one-way vs. two-way streetson traffic network performance (Gayah and Daganzo, 2012) and found that the capacity of two-way street networks could always be increased by simply restricting left turn movements at signalized intersections. The additional travel distance imposed by doing so is more than made up for by the additional capacity that would be available at signalized intersections, and this results in shorter vehicle travel times when the network is operating at capacity. However, because this study focused only on capacity conditions (i.e., the maximum throughput allowed by the networks), it failed to consider the full range of all anticipated traffic conditions, including both uncongested and congested states. Furthermore, this study only focused on static strategies in which one control scheme (either allowing or banning left turns) was applied at all times. This is a limitation as traffic networks are dynamic, and traffic control should also be dynamic to reflect the existing traffic conditions. In light of this, the current research examines the impact of accommodating or restricting left turn movements on traffic network performance across the full range of traffic states that can be expected. Grid networks of different sizes and with different link lengths were created and simulated in the Aimsun micro-simulation software to examine their performance under various left turn control strategies. The performance measures considered include: fuel consumption, vehicle emissions, and measures of traffic performancespecifically, using the Network Exit Function (NEF) and the Macroscopic Fundamental Diagram (MFD). These performance measures are calculated and presented as a function of the current traffic state, measured by the accumulation or number of vehicles using the traffic network. This can be used to easily identify accumulations for which left turns should be allowed or restricted. Additionally, this study also examines the benefits of allowing or restricting left turns dynamically based on the current traffic state. Overall, the results find that restricting left turns can be very beneficial as a network starts to become congested; however, restricting left turns actually reduces performance when the network is relatively empty. The optimal performance is thus achieved by allowing left turns when few vehicles are in the network and then restricting left turns when the network becomes more crowded. This dynamic strategy maximizes the traffic performance of the network at all times and results in the lowest vehicle travel times and reduced delays.

Available in PDF, EPUB and Kindle. Book excerpt: Global Practices on Road Traffic Signal Control is a valuable reference on the current state-of-the-art of road traffic signal control around the world. The book provides a detailed description of the common principles of road traffic signal control using a well-defined and consistent format that examines their application in countries and regions across the globe. This important resource considers the differences and special considerations across countries, providing useful insights into selecting control strategies for signal timing at intersections and pedestrian crosswalks. The book's authors also include success stories for coping with increasing traffic-related problems, examining both constraints and the reasons behind them. Presents a comprehensive reference on country-by-country practices on road traffic signal control Compiles and compares approaches across countries Covers theories and common principles Examines the most current systems and their implementation
