Claim:
1. A system for dynamically modifying lane configurations on a road segment, comprising: a plurality of dynamic lane markers disposed along the road segment that includes a beginning transition section, a main section and an ending transition section, arranged in that order along a travel direction of the road segment, the dynamic lane markers being arranged as a plurality of first rows of the dynamic lane markers and a plurality of second rows of the dynamic lane markers in the beginning transition section, the main section and the ending transition section, each of the plurality of first rows of the dynamic lane markers extending in the travel direction of the road segment and being spaced sequentially apart from each other in a widthwise direction of the road segment to represent a first number of first lanes each having a respective lane width, each of the plurality of second rows of the dynamic lane markers extending in the travel direction of the road segment and being spaced sequentially apart from each other in the widthwise direction of the road segment to represent a second number of second lanes each having a respective lane width that is less than the respective lane width of a narrowest one of the first lanes, the second number of second lanes being greater than the first number of first lanes, and the first and second rows of the dynamic lane markers are alternately positioned in the widthwise direction of the road segment; a plurality of beginning transitional dynamic lane markers disposed along the beginning transition section and extending in the travel direction of the road segment to form a plurality of beginning transitional rows of the beginning transitional dynamic lane markers that extend transverse with respect to the travel direction of the road segment and transverse to the first and second lanes to represent a plurality of beginning transitional lanes each having a beginning transitional width that decreases along the direction of travel from the beginning transition section to a boundary of the beginning transition section and the main section; a plurality of ending transitional dynamic lane markers disposed along the ending transition section and extending in the travel direction of the road segment to form a plurality of ending transitional rows of the ending transitional dynamic lane markers that extend transverse with respect to the travel direction of the road segment and transverse to the first and second lanes to represent a plurality of ending transitional lanes each having an ending transitional width that increases along the direction of travel from a boundary of the main section and the ending transitional section into the ending transition section; and a controller configured to determine whether a condition pertaining to the road segment exists, and in response to existence of the condition, control energization of the beginning transitional dynamic lane markers to define the beginning transitional lanes, control energization of the plurality of second rows of the dynamic lane markers to represent the second number of second lanes, and control energization of the ending transitional dynamic lane makers to define the ending transitional lanes.
