Traffic control in highway weaving sections is complicated since vehicles are crossing paths, changing lanes, or merging with through traffic as they enter or exit an expressway. There are two types of weaving section (a) single weaving sections which have one point of entry upstream and one point of exit downstream; and (b) multiple weaving sections which are based on lane detection fail to monitor weaving sections since they cannot track vehicles which cross lanes. The fundamental problem that needs to be addressed is the establishment of correspondence between a traffic object 'A' in lane 'x' and the same object 'A' in lane 'y' at a later time. For example, vision systems that depend on multiple detection zones simply cannot establish correspondences since they assume that the vehicles stay in the same lane. The motivation behind this work is to compensate for inefficiencies in existing systems as well as to provide more comprehensive data about the weaving section being monitored. We have used a vision sensor as our input. The rich information provided by vision sensors is essential for extracting information that may cover several lanes of traffic.
