Why Should Service Roads Yield to Main Roads?

[DaisyLynn]

Below are the reasons why service roads should yield to main roads: 1. Reason one: Main roads have higher traffic volume and serve as arterial roads, while service roads are secondary roads. Secondary roads should yield to arterial roads. Generally, main roads have more lanes and higher speed limits, so vehicles on service roads must yield to those on main roads. 2. Reason two: When traffic volume on main roads is too high, creating significant pressure, some vehicles can use service roads to alleviate congestion on main roads, such as at interchanges. 3. Reason three: In urban expressways, service roads should be located on one or both sides of the main road. For elevated roads, service roads should be placed at ground level beneath the elevated structure and should preferably be continuous in urban areas. In suburban expressways, service roads can be continuous or intermittent. Service roads on both sides of the main road should be one-way, while those on a single side can be two-way.
