Beginning with descriptions of parameters that characterize the flow of vehicles on freeways, arterial roads, and feeder routes, this hands-on book examines intrusive and non-intrusive traffic sensors and associated technologies that measure traffic flow and assist in the management of congestion. You get the latest information about sensors that provide wider coverage areas and a larger variety of traffic flow parameters than the more conventional inductive loops. The operating characteristics of these measuring devices is illustrated through detailed discussions of traffic-responsive arterial signal control, freeway incident detection, ramp metering, electronic toll and traffic management, commercial vehicle operations, advanced traveler information systems, and sensor installation and maintenance issues. Written by an acknowledged authority in the field, Sensor Technologies and Data Requirements for ITS is a convenient reference and textbook that includes valuable information about the functioning of video image processor, microwave radar, infrared, laser radar, ultrasonic, acoustic, magnetic, and inductive loop sensors. The evolution of modern toll tag technology standards and weigh-in-motion sensors are also treated. The book reviews the role of sensors in intelligent transportation systems for mitigating congestion, secondary incidents, travel delays, pollution, and excess fuel consumption. It gives you a convenient analysis of traffic detector data, traffic flow characteristics, sensor performance as measured as part of several U.S. Federal Highway Administration programs, and factors that contribute to measurement errors. This information is expertly associated with traffic sensor technologies currently in existence or soon to come on the market, and it delivers the data you need to plan and design today's intelligent transportation systems, as well as those in the future. The book is referenced with over 140 illustrations and 135equations, including descriptions of algorithms used to support traffic management functions. It helps you select the best sensors for your needs and contains tables that show current sensor applications in traffic management systems and lists of sensor vendors, sensor performance, and interface characteristics.
