Evaluation of Bus Operation Efficiency Based on Data Acquisition and CCR Model-Take Xi'an City As An Example

The article collects the daily passenger flow of 10 selected bus lines during peak hours through the “vehicle investigation”, then process the data to eliminate useless data. To support the national “bus first” policy, the operation efficiency of bus routes is evaluated. This essay introduces the DEA index evaluation system to frame out the five influencing factors of road transportation, i.e the line attribute, transportation capacity, passenger feedback, etc. Ten bus lines in Xi'an are selected, combined with the known network parameters and map ranging function, using the ratio of input and output indicators of CCR formula, then simplify it to a linear planning model. Finally, matlab programming algorithm is used to determine the efficiency value of each bus line, then put forward suggestions for improvement of the lines that have not achieve effectiveness.
