road design
Highway layout discipline
Road design is the engineering discipline concerned with planning and constructing roads, encompassing elements like lane width, curvature, grade, drainage, and sight lines.
The term covers both the process of creating these plans and the resulting configuration of a roadway.
Good road design balances safety, traffic flow, cost, and environmental impact.
The accident rate dropped after they improved the road design at that intersection.
