What is the difference between a hump bridge and bridge head bump?
1 Answers
The difference between a hump bridge and a bridge head bump lies in that the sign for a hump bridge is a raised arch bridge, used to remind drivers to drive carefully. Located at an appropriate position before the hump bridge, it has a large arch that affects sight distance, whereas a bridge head bump is a sign of uneven road surface, represented by two bumps instead of an arch bridge. The so-called bridge head bump is not simply understood literally as the dangerous act of driving a vehicle to the bridge head and jumping. The true meaning of bridge head bump is the phenomenon where vehicles experience bumps when passing due to uneven settlement at the bridge head and expansion joint (bridge head approach) or damage to the expansion joint, resulting in steps on the road longitudinal slope. It is a common issue in road quality, caused by inconsistent settlement between the bridge abutment and the embankment, leading to bumps and jumps when vehicles pass the junction between the bridge and the roadbed. When seeing signs of bumps ahead at the bridge head, one should slow down to avoid the impact of bumps on driving comfort and improve passing safety. However, passing quickly will increase wear on the vehicle's steering and transmission mechanisms, leading to increased fuel consumption. When seeing the sign for a hump bridge, one should drive on the right and slow down. Additionally, road narrowing warning signs, traffic flow warning signs, and road condition warning signs are also set up.
