Book excerpt: The major problems that attracted the researchers during the past years are increasing traffic in urban and sub-urban areas. Traffic varies over time and place. It is necessary to understand and be able to monitor all of these activities and changes in travel to make correct decisions about the design, operation, and maintenance of roadways. Traffic congestion can be detected in sequences of optical images in different ways. Trying to detect each individual vehicle and then to estimate its velocity does not sound a good approach. This theoretical vehicle density is directly related to the average vehicle velocity on the road segment and thus the information about the traffic situation, e.g. the existence of congestion, the beginning and end of congestion, the length of the jam, actual travel time, and so on can be derived. Since the construction of paved roads, we have struggled with ways to record vehicular movement. Not only is this information required for proper design of roadways, but also new intelligent transportation systems (ITS) require real-time knowledge of traffic movement to be effective. Highway Traffic Monitoring presents the state of the art and the practice and a look to the future trends in highway traffic monitoring. It describes methods of assessing the performance and reliability of traffic-counting equipment, including the evaluation of any bias within the results. It also covers the related issues such as commissioning, validation, verification, reliability, technology and test procedures. Traffic control and monitoring using video sensors has drawn increasing attention recently due to the significant advances in the field of computer vision. Many commercial and research systems use video processing, aiming to solve specific problems in road traffic monitoring. The focus of this guide is on the collection of traffic statistics, such as speed and traffic loads; identify dangerous situations, such as objects falling, animals or traffic jams.

Download or read book ITS Sensors and Architectures for Traffic Management and Connected Vehicles written by Lawrence A. Klein and published by CRC Press. This book was released on 2017-08-07 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: An intelligent transportation system (ITS) offers considerable opportunities for increasing the safety, efficiency, and predictability of traffic flow and reducing vehicle emissions. Sensors (or detectors) enable the effective gathering of arterial and controlled-access highway information in support of automatic incident detection, active transportation and demand management, traffic-adaptive signal control, and ramp and freeway metering and dispatching of emergency response providers. As traffic flow sensors are integrated with big data sources such as connected and cooperative vehicles, and cell phones and other Bluetooth-enabled devices, more accurate and timely traffic flow information can be obtained. The book examines the roles of traffic management centers that serve cities, counties, and other regions, and the collocation issues that ensue when multiple agencies share the same space. It describes sensor applications and data requirements for several ITS strategies; sensor technologies; sensor installation, initialization, and field-testing procedures; and alternate sources of traffic flow data. The book addresses concerns related to the introduction of automated and connected vehicles, and the benefits that systems engineering and national ITS architectures in the US, Europe, Japan, and elsewhere bring to ITS. Sensor and data fusion benefits to traffic management are described, while the Bayesian and Dempster–Shafer approaches to data fusion are discussed in more detail. ITS Sensors and Architectures for Traffic Management and Connected Vehicles suits the needs of personnel in transportation institutes and highway agencies, and students in undergraduate or graduate transportation engineering courses.
