On-Road i-Vics Management for Blockage of Abreast Low Speed Vehicles Near Signalized Intersections
Driving at velocity much lower than the speed limit greatly restraints the movements of the followers, resulting in considerable waste of road resource every day. When two slow vehicles are moving abreast on the city road, the result is devastating for their followers. To solve such problem by the idea the i-Vics (intelligent vehicular infrastructure cooperative systems), this paper proposes a dedicated on-road traffic management plan for abreast low speed connected vehicles, especially for scenarios near signalized intersections. The management plan takes three steps to erase the traffic blockage caused by those abreast slow drivers, including detection of abreast slow drivers, appraisal of environmental factors, and traffic guidance notification for all relevant drivers. In the proposed plan, the detection model initially evaluates the whole street and picks out all the abreast low speed vehicles based on the i-Vics. For every blockage target, a appraisal model of the surroundings determines the strategy how to dissolve the traffic blockage, including the feasibility of overtaking, and possibility of passing through the intersection and etc. Finaly, once the dissolving strategy is approved by the appraisal program, the management system sends notification of speed guidance to all relevant drivers to guide them to pass through the signalized intersection within the remaining green time.
