Description and Preliminary Data from TRW’s Lane Change Collision Avoidance Testbed
TRW has built, under NHTSA contract, a fully automated data acquisition system for assessing the effectiveness of a lane change collision avoidance system. The system features two subsystems that allow for automated acquisition and analysis of data. The first is a scanning laser rangefinder which serves both as the collision warning sensor and collector of ground truth information. The second subsystem is an eye-tracker which outputs, at 30 Hz, the driver’s gaze direction. Preliminary data, taken at a test track and on local freeways using team members, have refined the parameters that make up the driver warning algorithm. The data is consistent with a keep out zone adjacent to and 30 ft. behind the car and a 3 second time to arrival for fast approaching vehicles.

Detection And Recognition Of End-Of-Speed-Limit And Supplementary Signs For Improved European Speed
We present two new features for our prototype of European Speed Limit Support
system: detection and recognition of end-of-speed-limit signs, as well as a framework or detection and recognition of supplementary signs located below main signs and modifying their scope (particular lane, class of vehicle, etc…). The end-of-speed-limit signs are globally-recognized by a Multi-Layer Perceptron (MLP) neural network. The supplementary signs are detected by applying a rectangle-detection in a region below recognized speed-limit signs, followed by a MLP neural network recognition. A common French+German end-of-speed-limit signs recognition has been designed and successfully tested, yielding 82% detection+recognition. Results for detection and recognition of a first kind of supplementary sign (French exit-lane) are already satisfactory (78% correct detection rate), and our framework can easily be extended to handle other types of supplementary signs. To our knowledge, we are the first team presenting results on detection and recognition of supplementary signs below speed signs, which is a crucial feature for a reliable Speed Limit Support.

Developing A Fog Detection And Warning System
The California Department of Transportation (Caltrans) has implemented a fog detection and
warning system on Highway 99 near Fresno. The entire central valley region is susceptible to
Tule fog, which can reduce visibility tremendously, sometimes to near zero. This area has
experience numerous multiple vehicle crashes because of the fog, most recently in 2007, when a 108 car pile-up caused two deaths and nearly 40 injuries, and closed the highway for more than twelve hours. The fog detection system, which was installed last winter, uses speed and visibility detectors to assess road conditions, traffic management software to process data and control the field devices, and changeable message signs to provide information to the traveling public.

Developing Value Chains For Co-Operative Services – Safety And Convenience Services
COOPERS, an EC FP6 funded IP deals with Co-operative Systems, enabling the
communication of real time data between infrastructure and vehicle. The main objective of
this undertaking is to increase road safety and road efficiency. Value Chain activities and the
building of an appropriate business model are key elements in the project.
This paper shows the main actors for a Value Chain in the Co-operative Systems context. It
reveals that besides traditional roles, such as content provider, content aggregator, service
provider, and data distributor also new roles, such the role of a data clearance body is needed.
In the example analysed in this paper, a differentiation is made between a Value Chain for
Safety Critical Services, and Convenience Services is made. In the Safety Critical Services
case, a Traffic Control Centre plays the leading role, whereas in the case of the Convenience
Services a Telco takes over the lead.
