During peak congestion periods, buses operate on specially designated road shoulders (albeit at speeds significantly lower than limits posted for the adjacent highway). This allows buses to bypass congested roadways, enabling the bus to maintain its schedule regardless of traffic conditions. One of the problems faced by drivers using the shoulders is that the shoulders are typically no more than 3.1 m wide; a 12 m long transit bus measures 2.9 m across the rear view mirrors, and 2.6 m across the rear dual wheels. These narrow lanes require that a driver maintain a lateral error of less than 0.15 m to avoid collisions. This is a difficult task under the best conditions, and degrades to nearly impossible during conditions of bad weather, low visibility, high traffic congestion, etc. Metro transit drivers are not required to use the shoulders; shoulder use is left to their discretion. When poor conditions are encountered, many drivers choose not to use the shoulder. However, these poor conditions offer the greatest benefit of the bus-only shoulder use, creating an operational paradox. To minimize the effect of poor conditions on the use of bus-only shoulders, a lane assist system has been developed by the Intelligent Vehicles Lab at the University of Minnesota to help bus drivers under these difficult conditions. The system uses carrier phase, dual frequency differential GPS, a lane-level, high density, high accuracy geospatial database, and a lateral control algorithm for lateral assistance, radar for obstacle detection (critical in low visibility), and graphical, haptic, and tactile driver interfaces to provide guidance information to a driver. In addition to the system description, performance of the system on a operational bus-only shoulder is provided.","PeriodicalId":239269,"journal":{"name":"Proceedings.

While present sensor systems mainly focus on the validated detection of conventional crash partners like other vehicles or poles, there is still a lack for a reliable and cost efficient solution for the detection of pedestrians. In this context, a passive infrared system is a viable alternative mainly due to its affordability and environment-friendliness. A pedestrian detection system based on infrared (IR) sensors is presented. The system consists of an array of thermopile sensors which are arranged on the front bumper of the automobile in a way that the region of interest (ROI) is covered by the sensors field of view (FOV). Since thermopiles do not provide distance information, the sensor arrangement should also facilitate object localization. The optimal sensor arrangement is computed through an optimization algorithm. However, for an accurate position estimation, the sensor arrangement should be supported by suitable probabilistic techniques. For this reason, an approach was developed to map the measurements by means of a sensor model to an occupancy grid. The grid contains a probabilistic value in each cell and is ego-motion compensated. The combination of the optimized sensor arrangement and the occupancy grid technique are discussed here and a reliable method for the position estimation of pedestrians is presented.","PeriodicalId":239269,"journal":{"name":"Proceedings.
