Description
R1
Conditional smart highway
Conventional highway without any digital facilities
R2
Preliminary smart highway
Highway with some precollected static data (road alignment, marks, signs, etc.), which provides basic map functions.
R3
Partial smart highway
R2 highway + the ability of collecting the transient static data (pavement performance, maintenance, activities, etc.) and limited transient dynamic data, which provides some primary environment information for vehicles.
R4
Conditional smart highway
R3 highway+the ability of sensing the transient dynamic data (congestion, signal, etc.) and limited highly dynamic data, which enhances the vehicles perception towards road infrastructures.
R5
Full smart highway
R4 highway+the ability of sensing the highly dynamic data (trajectory, vehicle movements, etc.) Which provides complete elements awareness and cooperative driving. R5 highway can control and optimize the traffic flow from a macro perspective
