Research on Alignment Consistency of Highways with the Basis of 85MSR

The alignment consistency of highways is an important guarantee for vehicle safety. In this thesis, by comparing the computing methods of ΔV85 and 85MSR, the author concludes that 85MSR is a more appropriate way to evaluate the highway alignment consistency. The author studies Ningfu section on Heda superhighway with 85MSR, pointing out the section with poor alignment consistency, and provides basic data for the analysis and prevention of this section and road improvement.
