Intelligent vehicles are beginning to appear on the market, but so far their sensing and warning functions only work on the open road. Functions such as run-off-road warning or adaptive cruise control are de-signed for the uncluttered environments of open high-ways. We are working on the much more difficult problem of sensing and driver interfaces for driving in urban ar-eas. We need to sense cars and pedestrians and curbs and fire plugs and bicycles and lamp posts; we need to predict the paths of our own vehicle and of other moving objects; and we need to decide when to issue alerts or warnings to both the driver of our own vehi-cle and (potentially) to nearby pedestrians. No single sensor is currently able to detect and track all relevant objects. We are working with radar, ladar, stereo vision, and a novel light-stripe range sensor. We have installed a subset of these sen-sors on a city bus, driving through the streets of Pitts-burgh on its normal runs. We are using different kinds of data fusion for different subsets of sensors, plus a coordinating framework for mapping objects at an abstract level.
