【正文】 mated vehicle identification) systems used barcodes affixed to each vehicle, to be read optically at the toll booth. Optical systems proved to have poor reading reliability, especially when faced with inclement weather and dirty vehicles.? Most current AVI systems rely on radiofrequency identification, where an antenna at the toll gate municates with a transponder on the vehicle via Dedicated Short Range Communications (DSRC).High occupancy toll lanes? High occupancy toll lanes (HOT lanes) is a road pricing scheme that gives motorists in singleoccupant vehicles access to highoccupancy vehicle lanes (or HOV lanes). Typically, these tolls increase as traffic density and congestion within the tolled lanes increases, a policy known as congestion pricing. The goal of this pricing scheme is to minimize traffic congestion within the lanes.Cordon zones with congestion pricing? The main objective of this charge is to reduce traffic congestion within the cordon area. This fee or toll is charged automatically using electronic toll collection or automatic number plate recognition, since stopping the users at conventional toll booths would cause long queues, long delays, and even gridlock (市區(qū)交通大堵塞 ).Congestion pricing gantry at North Bridge Road, Singapore.Cordon zones (管制區(qū) ) have been implemented in Singapore, Stockholm, and London, where a congestion charge or fee is collected from vehicles entering a congested city center.Variable speed limitsVariable speed limits which change with road congestion and other factors. Typically such speed limits only change to decline during poor conditions, rather than being improved in good ones.Example variable speed limit sign in the United States.Emergency vehicle notification systems? The invehicle eCall is an emergency call generated either manually by the vehicle occupants or automatically via activation of invehicle sensors after an accident. When activated, the invehicle eCall device will establish an emergency call carrying both voice and data directly to the nearest emergency point. The minimum set of data contains information about the incident, including time, precise location, the direction the vehicle was traveling, and vehicle identification.Cooperative systems on the road? Communication cooperation on the r
