Effects of First Class Highway Roadside Interference on Operating Speed

The goal of the research was to study one of the most important effects of first class highway operating efficiency-roadside interference. First Class highway is a special type of road, which is unknown in other countries; they are similar to multi-lane road. In this research, operating speed on First Class highway is analyzed based on the peculiar influencing factor-roadside interference in China. This factor did not exist when the first class highway was built; however with the rapid development of the Chinese economy, the scope of the city is increasing gradually. The surrounding environment of the highway has been changed time to time. So, the roadside interference (such as pedestrians, bicycles, etc.) changes the original function of the highway. In order to collect enough data, the experimental study includes two aspects: subjective and objective method. According to the influencing degree of roadside interference on operation efficiency, the roadside classification is achieved, which can be theoretical reference for First Class highway construction in the future.
