DOWNLOAD EBOOK →Intelligent Transportation Systems: Functional Design for Economical and Efficient Traffic Management provides practical guidance on the efficient use of resources in the design of ITS. The author explains how functional design alternatives can meet project objectives and requirements with optimal cost effectiveness and clarifies how transportation planning and traffic diversion principles relate to functional ITS device selections and equipment locations. Methodologies for translating objectives to functional device types, determining device deployment densities and determining the best placement of CCTV cameras and message signs are provided, as are models for evaluating the benefits of design alternatives based on traffic conditions. Readers will learn how to reduce recurrent congestion, improve incident clearance time in non-recurrent congestion, provide real-time incident information to motorists, and leverage transportation management center data for lane control through important new active transportation and demand management (ATDM) methods. Finally, the author examines exciting developments in connected vehicle technologies, exploring their potential to greatly improve safety, mobility and energy efficiency. This resource will greatly benefit all ITS designers and managers and is of pivotal importance for operating agencies performing evaluations to justify operational funding and system expansions.

Thus, this project involved developing the methods necessary to systematically describe, explain, and predict the flow of traffic with respect to time and space. The utility of this knowledge was demonstrated in routing voluminous traffic. Achieving these objectives required the collection, management, and analysis of traffic data concerning volume, speed, and traffic sensor occupancy. Management of this data required the design and implementation of a large scale database management system as well as assuring the quality of the collected data. Descriptive, explanatory, and predictive statistical models were developed to help gain the desired understanding of traffic flow. Application efforts focused on the Detroit metropolitan area. Traffic data was regularly obtained from the Michigan Intelligent Transportation System Center. Statistical models of traffic flow in the Detroit area I-75 corridor were constructed. A previously developed routing model was extended and adapted to the I-75 corridor and the newly developed statistical models incorporated to help compute traffic flow metrics. Both a software solver and a hardware solver for the model were implemented. In addition, a framework for traffic simulation was developed and applied to the development and calibration of a micro-simulation model including the same part of the I-75 corridor. This model was used to demonstrate the benefits of guidance in re-routing traffic as a result of a traffic incident.
