- Abstract:
- In order to avoid the waste of public transport capacity along the track, it is necessary to adjust the conventional bus lines along the track. First, starting from the spatial relationship between the common public transport and rail transit, the transfer relationship between the regular bus passengers and the rail transit was analyzed. Secondly, the characteristics of the passenger flow of the conventional bus lines with low time utility of the common bus segments were analyzed, and further analysis of the station space relationship of common line segments to determine whether the common bus line segment was retained, by evaluating the important station importance degree of the upper and lower bus routes to be adjusted respectively. Finally, whether the bus lines and stations were important lines and stations by means of station importance and confidence level were determined, and whether the end line was reserved by combining the length of the end line was determined. The results show that after the cancellation of the common segment of the conventional bus lines, the passenger flow will be directly transferred to rail transit, which reduces the capacity waste of the conventional bus, cultivates passenger flow for the rail transit at the early stage of operation and promotes the efficiency of the rail transit. The conventional bus endpoint line retain after the adjustment has increased by nearly 2 times during the peak period due to the newly added transfer passenger flow. This also illustrates the practical significance of judging the endpoint line as a rail transit feed line based on the importance of the station. This method calculates the importance of stations based on the passenger flow distribution of conventional bus lines, evaluates the importance of segmented lines under collinear characteristics, and develops segmented adjustment plans. Therefore, the collinear and passenger flow characteristics of the conventional bus lines along the rail transit are taken into account by this method, which can be closer to actual needs. This research can provide a decisionmaking basis for the adjustment of conventional bus lines along the rail transit. 7 figs, 26 refs.
