This requires a lot of infrastructure, slows traffic unnecessarily at some locations (for example, by stopping each vehicle for a second or two) to optimize vehicle flow at other locations, and can lead to public disbelief at these locations. Annoyance with controls that actually offer some advantages but are considered cumbersome and unnecessary by the public

Abstract

The disclosure relates to a method and apparatus for congestion reduction through cooperative adaptive cruise control. A system includes a processor configured to determine traffic density over a road segment. The processor is also configured to model traffic parameters to maximize traffic flow over the road segment, based on the traffic density and travel characteristic data received from a plurality of vehicles exiting the road segment. The processor is further configured to determine a speed to density curve, using the model, that would maximize traffic flow and send the speed to density curve to a vehicle entering the road segment.

Description

technical field [0001] The illustrative embodiments relate generally to a method and apparatus for reducing congestion through cooperative adaptive cruise control. Background technique [0002] Traffic jams often start at restricted locations (such as bridges, tunnels, and construction sites) where multiple traffic lanes merge into a single lane or where drivers must remain in lanes passing through narrow areas (resulting in a lot of driving personnel slow down). While a little congestion may be harmless, around peak traffic hours this can snowball into severe congestion that can suddenly take hours to sort out on your own. [0003] It has been observed that with a varying number of vehicles per minute passing a point (vehicle flow) as a given number of vehicles per mile (vehicle flow), one can obtain Vehicle traffic (bumper to bumper traffic)) to achieve optimal flow. That is, if there is a way to control the number of vehicles spaced apart at a given interval (such as a...
