Evaluation of an active wildlife-sensing and driver warning system at Trapper's Point by Qiyue Dai( Book )

2 editions published in 2009 in English and held by 4 WorldCat member libraries worldwide

Collisions with wildlife are a serious concern on American highways. In Wyoming, the concern has prompted the Wyoming Department of Transportation to construct an experimental wildlife detection and driver warning system at Trappers Point, north of the town of Pinedale on US Highway 191. The focus of this thesis is two-fold: to develop a framework to determine whether the driver warning system is effective at modifying driver behavior and to develop a framework to determine whether the wildlife detection system reliably detects the presence wildlife on the roadside. Transportation agencies have attempted to solve the deer-vehicle collision problem with a wide variety of solutions. Published literature was reviewed to analyze the effectiveness of these solutions with a spotlight on other active, wildlife-detecting driver warning systems. The system at Trappers Point utilizes the Eagle Intrusion Detection System (EIDS), originally developed by Telonics, Inc for military applications. Seismic and passive infrared sensors are designed to detect the presence of wildlife and trigger the flashing lights atop six signs that read 'DEER ON ROAD WHEN FLASHING'. Many difficulties with the wildlife detection system and data collection equipment were experienced during this study. This report describes these problems in detail and analyzes the system using three measures of effectiveness: accurate detection of wildlife, changes in driver behavior, and crash reduction
Evaluation of high wind factors on truck rollover in Bordeaux, Wyoming by Qiyue Dai( )

1 edition published in 2009 in English and held by 2 WorldCat member libraries worldwide

The state of Wyoming has frequent severe wind conditions, particularly in the southeast corner of the state along Interstate 80 and Interstate 25. The high winds are problematic in many ways including, interfering with the performance of the transportation system, blowing vehicles off the road, or even overturning high profile trucks, which can cause economic losses and safety concerns for road users. The primary objectives of this research involve two parts: First, develop a statistical model that reveals the correlation between likelihood of overturning trucks and the weather conditions. Second, use the result of the statistical model to develop a data driven operation plan for Wyoming Department of Transportation (WYDOT) to use in the winter season at a hazardous high wind corridor to improve truck safety. Two logistic models were developed in this thesis. The second order interaction model performed better than the first one and revealed the correlation between the likelihood of overturning crash and weather parameters. A three operation-level high wind warning system was also developed for WYDOT to use to improve the truck safety in the hazardous high wind corridor
