road systems
Interconnected travel routes
Road systems are networks of interconnected routes for vehicle travel, encompassing highways, streets, and connecting infrastructure.
The term usually implies planned coordination—traffic signals, signage, maintenance schedules—rather than random paths: The city's road system was designed for horse-drawn carriages, not modern traffic.
Road systems range from local grids to national highway networks.
