    The traffic congestion will get worse when more people utilize their cars for their trips. So, the number of people using the buses will also decrease. It then results in the more use of cars. Therefore, it lends to the pollution of the environment. To reduce the traffic demands and improve the environment, the Kanagawa Prefectual Police HQ developed a public transportation priority systems (PTPS)... View full abstract»

    We consider optimal resolution of air traffic conflicts. Aircraft are assumed to cruise within a given altitude layer and are modeled as a kinematic system with velocity constraints and curvature bounds. Aircraft can not get closer to each other than a predefined safety distance. For such system of multiple aircraft, we consider the problem of planning optimal paths among given way-points. Necessa...

    Publication Year: 2000, Page(s):404 - 409
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (332 KB)

    We show the importance of a filtering step for real-time on-board applications such as the driver impairment detection system. Sampling on-board a vehicle produces noisy signals representing errors for the data processing module. Digital filtering is applied to signals from different sources including: lateral position, steering wheel angle and vehicle speed. Our filtering approach takes into acco... View full abstract»
