Congestion relief using dynamic lighted road lane markings
A system and method for providing increased traffic carrying capacity of a road, such as a highway, by modifying an existing roadway from, for example, four lanes to five lanes, to create an additional travel lane. The system and method dynamically changes the width of travel lanes using, for example, embedded pavement lights, or other lighting arrangements, in lieu of traditional painted lane lines. As traffic volumes increase and speeds decrease along the road, an intelligent transport system (ITS) sends a congestion signal to the overhead lane controls and dynamic message signs (DMS) along the entire road segment of interest. The posted speed limits are changed, and the lane markings are controlled to dynamically increase the number of lanes in the road segment to five, for example, of narrower widths until traffic volumes reduce and the number of lanes can be returned to four, for example, with normal speed limits.
1 . A system for integrating traffic flow to manage traffic capacity on a road segment, the system comprising:
a dynamic lane marking configuration comprising marking devices; and
a controller configured to control the dynamic lane marking configuration to energize the marking devices to represent a lane configuration on the road segment for use by standard operation vehicles, and to control transmission of information representing the lane configuration on the road segment for use by driverless vehicles.
2 . The system according to claim 1 , wherein
the controller is configured to control the dynamic lane marking configuration to switch between representing the lane configuration as including a first number of lanes, each having a first respective lane width, and a second number of lanes, each having a second respective lane width that is less than the first respective lane width, the second number of lanes being greater than the first number of lanes.
3 . The system according to claim 2 , wherein
the controller configured to determine whether a condition pertaining to the road segment exists, and in response to existence of the condition, control the dynamic lane marking configuration to switch between representing the lane configuration as including the first number of lanes and representing the lane configuration as including the second number of lanes.
4 . The system according to claim 3 , wherein
the condition represents a traffic condition relating to vehicle congestion in the road segment.
5 . The system according to claim 3 , further comprising:
a monitoring system configured to determine whether the condition pertaining to the road segment exists.
6 . The system according to claim 3 , wherein:
the controller is configured to at least one of the lanes as a fare lane requirement payment for usage.
7 . The system according to claim 3 , wherein:
the condition represents an emergency condition and one of the driverless vehicles or one of the standard operation vehicles is a vehicle responding to the emergency condition.
8 . The system according to claim 3 , wherein:
the condition represents a weather condition.
9 . The system according to claim 3 , wherein:
the condition represents a closure, obstruction or incident pertaining to the road segment.
