Research on Speed Limit of Highway Expansion Project Construction Zone

Abstract:

The reasonable speed limit would reduce the detrimental impact on the driving safety and traffic jam in Highway expansion project high slope work zone. The study based on the investigation of Liu Nan highway’s traffic capacity, speed, traffic flow and other related index, which researched the vehicles queuing length of the different lane width in expansion project construction zone. The result is that 1/2 lane occupied need limit speed step by step in the warning area, 1/3 lane occupied limit 60km/h and 1/4 lane occupied limit 80km/h.
