Field Test of Monitoring of Urban Vehicle Operations Using Non-instrusive Technologies
Author: Jim Kranig
Publisher:
ISBN:
Category : Detectors
Languages : en
Pages : 290
Book Description
This report documents the activities and results of a test of non- intrusive traffic detection technologies. Seventeen devices representing eight different technologies were evaluated in varying environmental and traffic conditions. The following technologies were tested: passive infrared, active infrared, magnetic, radar, doppler microwave, pulse ultrasonic, passive acoustic, and video. Testing was done at both freeway and intersection locations. Emphasis was placed on urban traffic conditions and locations that typify temporary counting locations. The evaluation also focused on the ease of system setup and use, general system reliability, and system flexibility.

Evaluation of Non-intrusive Technologies for Traffic Detection
Author: Erik Minge

ISBN:
Category : Automatic data collection systems
Languages : en
Pages : 100
Book Description
The use of non-intrusive technologies for traffic detection has become a widespread alternative to conventional roadway-based detection methods. Many sensors are new to the market or represent a substantial change from earlier versions of the product. This pooled fund study conducted field tests of the latest generation of non-intrusive traffic sensors. Sensors were evaluated in a variety of traffic and environmental conditions at two freeway test sites, with additional tests performed at both signalized and unsignalized intersections. Emphasis was placed on urban traffic conditions, such as heavy congestion, and varying weather conditions. Standardized testing criteria were followed so that the results from this project can be directly compared to results obtained by other transportation agencies. While previous tests have evaluated sensors' volume and speed accuracy, the current generation of sensors has introduced robust classification capabilities, including both length-based and axle-based classification methods. New technologies, such as axle detection sensors, and improved radar, contribute to this improved performance. Overall, the sensors performed better than their counterparts in previous phases of testing for volume and speed accuracy. However, the additional classification capabilities had mixed results. The length-based sensors were generally able to report accurate vehicle lengths. The axle-based sensors provided accurate inter-axle measurements, but significant errors were found due to erroneously grouping vehicles, affecting their ability to accurately classify trucks.
