[0002] With the acceleration of the urbanization process, the public transport system plays an important role in urban transportation. As a flexible form of public transport, buses with variable routes can adjust their operation routes according to demand to adapt to different passenger flows and traffic conditions. However, in actual operation, their operation time is affected by various factors, such as traffic congestion, passenger boarding and alighting time, road construction, etc. These factors may cause a deviation between the actual operation time of buses and the timetable, thus affecting the reliability of the bus system and the travel experience of passengers.

Especially for buses with variable routes, there is a lack of systematic and intelligent evaluation means. Traditional evaluation methods mostly rely on manual statistics and simple data analysis, and it is difficult to comprehensively reflect the resilience characteristics of bus operation time. Therefore, there is an urgent need for a method that can accurately evaluate the operation time resilience of buses with variable routes, so as to optimize bus operation scheduling, improve service quality, and provide a scientific basis for the planning and management of the public transport system.

Combining with the calculated resilience coefficient of the operation time of the bus vehicles on the whole line of variable routes , determine the resilience level of the operation time of the bus vehicles on this variable route.

[0034] The following further illustrates a method for intelligent evaluation of the resilience of the operation time of bus vehicles on variable routes according to the present invention through a specific example.

[0035] There are a total of 22 stations (including the starting and ending stations) on the section investigated in this embodiment. Among them, there are 12 fixed stations and 8 variable stations (the 3rd, 4th, 11th, 12th, 13th, 19th, 20th, and 21st stations are variable stations), as Figure 4 shown. The evaluation period is 30 days, and there are 48 shifts every day.

[0036] Step 1) Construct a dataset of the operation characteristics of bus vehicles on variable routes.

[0037] After on-site investigation, a subset of arrival time characteristic data of the operation schedule of buses with variable routes, a subset of actual arrival time characteristic data of buses with variable routes, and a subset of characteristic data of the number of on-vehicle passengers when buses with variable routes arrive are constructed. The investigation time is selected during the whole operation period of buses with variable routes. The operation schedule, actual arrival time, and the number of on-vehicle passengers when buses with variable routes arrive at this section are shown in Table 1 (only part of the data is listed taking the fixed station 1 as an example): Table 1 Operation schedule, actual arrival time, and the number of on-vehicle passengers when buses with variable routes arrive

[0038] Step 2) Calculate the operation time of buses with variable routes during the evaluation period.

[0039] 2-1) Divide the fixed station sections and variable station sections of buses with variable routes. The fixed stations of buses with variable routes divide the buses with variable routes into several fixed station sections, and the variable stations within each fixed station section divide the fixed station section into several variable station sections.

[0040] There are a total of 22 stations (including the starting and ending stations) in the section investigated in this embodiment. Among them, there are 12 fixed stations and 8 variable stations (the 3rd, 4th, 11th, 12th, 13th, 19th, 20th, and 21st stations are variable stations).

[0042] Step 3) Determine the weak sections of the operation time resilience of buses with variable routes.

[0043] 3-1) Calculate the operation time resilience deviation degree of buses with variable routes on the whole line and fixed station sections.

[0044] According to the actual operation time and schedule operation time of buses with variable routes on the whole line and fixed station sections, determine the operation time resilience deviation degree of buses with variable routes on the whole line and fixed station sections, as shown in Table 3: Table 3 Operation time resilience deviation degree of buses with variable routes on the whole line and fixed station sections

[0045] 3-2) Determine the vulnerable sections of the operation time resilience of variable-route bus vehicles.

[0046] As can be seen from Table 3, only the deviation degree of Section 12 of the fixed station is greater than the deviation degree of the whole line. Therefore, Section 12 of the fixed station is the vulnerable section of resilience and is re-numbered as the first section.

[0047] Step 4) Calculate the operation time resilience coefficient of the variable-route bus vehicles for the vulnerable sections of resilience.

[0048] 4-1) According to the number of on-vehicle passengers of variable-route bus vehicles arriving at the fixed stations and variable stations of the vulnerable sections of resilience during the evaluation period of 30 days and 48 shifts per day, it can be calculated that the average number of on-vehicle passengers of the variable-route bus vehicles arriving at the fixed stations of the vulnerable sections of resilience is 18, and the average number of on-vehicle passengers of the variable stations is 15.

[0049] 4-2) Calculate that the operation time resilience coefficient of the variable-route bus vehicles for this vulnerable section of resilience is 0.19.

[0050] Step 5) Evaluate the operation time resilience level of variable-route bus vehicles.

[0051] 5-1) Calculate that the operation time resilience coefficient of the variable-route bus vehicles for the whole line is 0.19 according to the operation time resilience coefficients of the bus vehicles for each vulnerable section.

[0052] 5-2) Use the operation time resilience coefficient of the variable-route bus vehicles for the whole line as the evaluation index of the resilience level, and divide the resilience level into three categories: good, general, and poor. The threshold between good and general can be taken as 0.2-0.3, and the threshold between general and poor can be taken as 0.6-0.8. According to the operation time resilience coefficient of the variable-route bus vehicles for the whole line calculated in S51, which is 0.19, it can be determined that the operation time resilience level of this variable-route bus vehicle is good.
