To gain noise reduction and unique environmental information detection object-hypotheses are evaluated. For each object an object-dynamic is built. The Object-dynamic consists of four one-dimensional neural fields for information evaluation of relative position, size and relative velocity. The chosen formulation enables fusion and separation of object-hypotheses gained from different sensors. Due to the dynamic character of the representation a reduction of noise and a prediction over short time periods is possible. The advantages of the representation are shown by inspecting real world sensor data.","PeriodicalId":365722,"journal":{"name":"Proceedings.

To avoid such drawbacks, a genetic fuzzy logic controller (GFLC) is proposed by employing an iterative evolution algorithm to promote the learning performance of logic rules and the tuning effectiveness of membership functions from examples In sequence. In addition, an encoding method is developed to overcome the difficulties in dealing with numerous constraints while employing genetic algorithms in tuning membership functions. A case of GM car-following behaviors is experimented to verify the applicability and robustness of GFLC. The results demonstrate that GFLC can predict the car-following behaviors precisely. Due to the similarity between fuzzy neural networks (FNN) and GFLC, a comparison is also made and the results indicate that GFLC performs superior to FNN.","PeriodicalId":365722,"journal":{"name":"Proceedings.

The fixed time signal control scheme is also compared with the fuzzy logic one in the simulation.

One key issue in this area is how to track the vehicles through the remote image sequences. This paper describes an adaptive motion correspondence algorithm for multiple vehicle tracking from air-borne remote cameras. The motion correspondence is established by searching over an extended correspondence matrix. An on-line confidence factor is assigned to each track to control the search strategy. Experiments with real traffic scenarios showed that the algorithm could automatically distinguish track initiation from false detection, as well as track termination from occlusion, which demonstrated its feasibility for real-time applications.","PeriodicalId":365722,"journal":{"name":"Proceedings.

Four parameters, including the update cycle of the metering rate, a constant regulator, the location and desired occupancy of the downstream detector station, are considered.
