      <title>Enhanced Camera/Video Imaging Systems (E-C/VISs) for Heavy Vehicles: Final Report</title>
      <link>https://trid.trb.org/View/1136509</link>
      <description><![CDATA[Tests were performed to determine the feasibility of developing an Enhanced Camera/Video Imaging System (Enhanced C/VIS or E-C/VIS) to provide heavy-vehicle drivers with better situation awareness to the sides and rear of their vehicles. It is well known that large blind spots currently exist in these areas and that sideswipe crashes can occur as a result. An additional goal was to extend the operating envelope of conventional video to nighttime and to inclement weather. A three-channel system was envisioned in which there would be a camera at each (front) fender of the tractor looking backward along the sides of the rig. The third channel would be aimed rearward from the back of the trailer. The current document describes the project results. Indoor tests involved selection of components having the best capabilities, while early outdoor tests used the selected components in a single-channel side mounted system. Subjects evaluated rain and dark conditions. Results were satisfactory. Once developed, the three-channel system was tested and found to work well in the nighttime and inclement weather environments. Street lighting was also included in the testing.]]></description>

      <title>Field Demonstration of Heavy Vehicle Camera/Video Imaging Systems: Final Report</title>
      <link>https://trid.trb.org/View/1136515</link>
      <description><![CDATA[To help drivers monitor the road and to reduce blind spots, Camera/Video Imaging Systems (C/VISs) display video from cameras mounted on the truck’s exterior to drivers using displays inside the truck cabin. This report investigated drivers’ performance with C/VISs in a real-world trucking operation. Twelve commercial drivers’ performance with and without a C/VIS was continuously recorded while they each drove for four months. Half of the drivers used a commercially available C/VIS that had a side-view camera on each fender. The other drivers used an advanced C/VIS (A-C/VIS) that had side-view cameras, a rear-view camera, and night-vision capabilities. The results show that when a C/VIS was provided: 1) drivers’ involvement in safety-critical events (SCEs) did not change, 2) the probability that drivers looked forward did not change, 3) drivers were more likely to use the C/VIS at night and when making right lane changes, and 4) drivers indicated that the C/VISs helped them become aware of surrounding objects and merge into traffic. In terms of disbenefits, some drivers indicated that glare from the commercially available C/VIS monitors, as positioned to specifications, could be uncomfortable at night. The A-C/VIS’s advanced features were highly rated by drivers. The rear-view camera was also used more than the left or right fender cameras.]]></description>

      <title>EVALUATION OF SYSTEMS TO MONITOR BLIND AREAS BEHIND TRUCKS USED IN ROAD CONSTRUCTION AND MAINTENANCE: PHASE 1</title>
      <link>https://trid.trb.org/View/702925</link>
      <description><![CDATA[The majority of fatalities that occur in road construction work zones in the United States involve a worker being struck by a piece of construction equipment or other vehicle. The Spokane Research Laboratory of the National Institute for Occupational Safety and Health, in cooperation with the Washington State Department of Transportation, is evaluating methods to decrease these accidents. One such method uses devices that assist equipment operators in monitoring blind areas around the equipment to prevent collisions with workers on foot or other objects. Several cameras and sensor systems are available for this application, and a study was conducted to evaluate these systems on various trucks used in road construction and maintenance. Tests were conducted using sanding trucks during the winter months, which allowed researchers to investigate the effectiveness and limitations of various technologies under the most extreme conditions. Tests were also conducted using dump trucks during the warmer months to study the effectiveness of the systems in highway work zones. Results show that many difficulties arise when using camera and sensor systems in cold, snowy climates. And, while the operation of these systems is more reliable during the warmer months, challenges still exist in using them on equipment in crowded work areas.]]></description>
