Safety

Prior to the introduction of tire pressure monitoring systems, it was very difficult to perform a comprehensive study of tire pressures and tire pressure maintenance on our customer’s vehicles.  Using GM’s OnStar system and GM’s tire pressure monitoring system (which is now installed on a wide range of vehicles to meet FMVSS 138 requirements), we are able to survey a large number of customers, in real-time, on a continuous basis. This study is limited to subscribers of OnStar Vehicle Diagnostic monthly email service who have vehicles with a tire pressure monitoring system. It provides insights on the tire pressure maintenance behavior of owners relative to seasonal temperature variations, oil changes, accumulated miles, vehicle age, and vehicle type.

To deter dangerous driving, we recently proposed a safe driving promotion system, which displays real-time driving scores and rankings to drivers. Thus, it is reasonable that our system will rouse a competitive spirit, which will improve driving behavior. In this study, the effect measurement of our system was carried out using a driving simulator. Time gaps, the frequency of sudden deceleration, and the number of lane changes were compared using four conditions: control, slogan, warning, and competition conditions. The results of the experiment suggest that the competition condition, which simulated our proposal, most effectively deters dangerous driving.

In ITS, safety is a considerable topic to be tackled by society as a whole, and various IT applications have been launched in Japan. We, Fujitsu, are  trying to apply technology of a millimeter-wave radio radar developed for vehicles and look for new business opportunities. In these activities, focusing on reducing the number of traffic accidents involving pedestrians, we have developed a pedestrian-detection sensor by improving the isolation capability of this millimeter-wave radar. As future applications for this sensor, we promote two systems, such as a next-generation system to detect obstacles on railroad crossings  and sensor to detect pedestrians crossing roads. Both systems will contribute to the safety of operating trains, driving vehicles and for pedestrians. In this  paper, the structure and  characteristics of the sensor and its applications are presented.

Managing the transportation system capacity during mass evacuations in response to
hurricanes and severe weather systems is complex.  The Louisiana DOTD is
implementing a road weather management system to help address this problem.  The
solution integrates LaDOTD road information and weather in a GIS framework.  One of
the unique capabilities of the system is the calculation current and forecast road travel
time conditions based on current and forecast weather.  Integration in a GIS also provides
the abilities to push proactive alerts and publish real-time road weather maps to decision
makers.  This paper will discuss implementation experiences and initial impacts of the
system.

The Oregon Department of Transportation undertook a critical review of their incident management program in the Portland Metropolitan area and concluded that certain technical and operational changes were needed to improve daily operations in incident management and to reduce operations and maintenance costs. At the heart of the revamped incident management program was a planned upgrade to the Transport Advanced Transportation Management System. The ATMS is a valuable tool in the overall strategy of highway incident management in the Portland region and its upgrade would provide an excellent return on investment for both incident management effectiveness and maintaining a reasonable level of recurring costs to operate certain automated incident management tools. As part of the planned Release 2 of the ATMS, the AVL and alpha-numeric paging functions are being integrated into the ATMS software, and operator Graphical User Interfaces are being enhanced to provide more data and more efficient data entry capabilities. These upgrades in turn necessitated installing new AVL and Paging subsystems to improve reliability and provide an easier path to integration into the ATMS. The result will be an improved incident management program operated at a lower recurring cost.
