Intelligent Work Zone Using Automatic Queue Detection Systems
| 项目名称： | Intelligent Work Zone Using Automatic Queue Detection Systems |
| 摘要： | The proposed research will evaluate the efficacy of the Nebraska Department of Transportation (NDOT) Automatic Queue Detection (AQD) system. The test beds for this study will be located at various work zones on Interstate 80 in Nebraska. It is anticipated that four (4) sites will be studied. The effectiveness of the AQD systems will be verified quantitatively. A statistical analysis of crashes at work zones that are equipped and not equipped with the AQD system will be undertaken. In particular, the researchers will examine whether the AQD system had improved safety, e.g., a measured reduction in rear‐end crashes. The research will also examine whether other types of crashes increased (or not). The study will also observe driver behavior as a function of the PDMS messages. In particular, the reduction in speed, if any, for the various sign messages will be quantified. Lastly, NDOT uses a cost‐benefit analysis when deciding whether to deploy an AQD system at a work zone. This research will validate the assumptions underlying this benefit/cost methodology. |
