| Abstract: | According to the test data of the speed of buses running on several routes in Beijing,this paper analyzes the factors affecting the average speed of buses.After studying three calculation methods of the average bus speed,the weighting method is regarded as the best one.By summarizing the distribution of average speed on different types of road and the statistical distribution rule,it is concluded that the distribution of average bus speed in Beijing follows the law of logarithmic normal distribution.The study provides a scientific basis for the type selection of electric buses,the determination of operation mode and the analysis of operation costs for Beijing public transportation. |
