Description

A planning method for the optimal travel scheme of intelligent shared bicycles and public transportation

technical field

The invention belongs to the technical field of traffic planning and intelligent technology application, and in particular relates to a planning method for an optimal travel scheme of intelligent shared bicycles and public transportation.

Background technique

As a basic national policy of our country, bus priority has encountered various problems in the practice process, among which "difficulty in transferring" is a major problem hindering public transport travel. The problem of "difficult transfer" is mainly manifested in two aspects: long transfer time and poor transfer convenience.

The emergence of shared bicycles is conducive to solving the "last mile" travel problem of urban traffic, which greatly improves the convenience of transfer. The distance from the bus and rail transit station to the destination of the origin of the trip often causes a lot of inconvenience due to problems such as time-consuming, congestion, and direct travel. It takes a long time to walk, and the economy of private bicycles Safety issues and the fixed limitations of the rental points of public bicycles will cause travel inconvenience. Shared bicycles can alleviate this travel phenomenon due to their strong accessibility, high safety factor, green environmental protection, low cost of use, and good flexibility, which greatly improves the convenience of transfers.

The emergence of shared bicycles improves the transfer environment on the one hand, and on the other hand, it also forms a certain competition with public transportation to a certain extent, especially the competition with conventional buses in short- and medium-distance travel. In addition, shared bicycles also have a large degree of inefficient utilization and excessive abuse. Therefore, how to reasonably plan the functional positioning of shared bicycles in the urban transportation system and how to make shared bicycles better serve the development of public transportation , How to make the emergence of shared bicycles can better solve the problems of hierarchical travel and collocation of urban traffic should be analyzed and solved.

The bus impedance function index includes three indicators: the time, cost and convenience of passengers traveling on public transport lines. The bus impedance value is determined by the following formula:

Detailed ways

The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[Example] It is known that after a large-scale traffic travel survey and travel psychology analysis of residents in a certain city, the maximum acceptable walking distance for residents in this city is 1.5km, and the average maximum acceptable cycling distance for the public is 3.5km;

The influence coefficients of the time spent in different travel modes are: walking: A ₁₁ = 6.5/(10min), shared bicycle: A ₂₁ = 3/(10min), regular bus: A ₃₁ = 1.2/(10min), subway : A ₄₁ =1.0/(10min);

The average operating speeds of different travel modes are: peak hours: walking V ₁ =3.5km/h, shared bicycle V ₂ =7km/h, regular bus V ₃ =18km/h, subway V ₄ =35km/h; Peak hours: walking V ₁ =3.5km/h, shared bicycle V ₂ =8km/h, regular bus V ₃ =28km/h, subway V ₄ =35km/h;

The travel cost influence coefficients of different travel modes are: peak hours: walking A ₂₁ = 0, shared bicycles A ₂₂ = 4, regular bus A ₃₂ = 1.2, subway A ₄₂ = 1; non-peak hours, walking A ₂₁ = 0, shared bicycle A ₂₂ =3, bus A ₃₂ =1.8, subway A ₄₂ =1.5.

The travel costs of different travel modes are as follows: the average cost of shared bicycles is 0.5 yuan per person, that is, x ₂₂ = 0.5, the average price of conventional buses is 1 yuan per person, that is, x ₃₂ = 0.5, and the average price of the subway is within 0-3km 2 yuan, 3 yuan within 3-5km, 4 yuan within 5-10km, 5 yuan for the part exceeding 10km but less than 15km, 6 yuan for the part exceeding 15km; that is, the subway is within 0-3km, x ₄₂ = 0.5, The subway taken within 3-5km x ₄₂ = 3, the subway taken within 5-10km, x ₄₂ = 4, the subway taken within 10-15, x ₄₂ = 0.5;

The influence coefficients of different travel modes are, peak hours: walking A ₁₃ = 2, shared bicycle A ₂₃ = 2.5, regular bus A ₃₃ = 5, subway A ₃₄ = 2.5; off-peak hours: walking A ₁₃ = 1.5, shared bicycle A ₂₃ =1.5, regular bus A ₂₃ =3, subway A ₂₃ =2.5;

Combined with a specific case, use the built-in system of shared bicycle software based on GPS navigation to plan and recommend the optimal travel plan.

(1) It is known that the starting point location and the destination location obtained by the traveler using the built-in GPS software of the shared bicycle are shown in the mobile App as shown in Figure 3. Try to analyze the analysis process of the built-in system and determine the optimal travel plan.

According to GPS navigation, the shortest distance from the travel origin to the travel destination is 1.2km, which is less than the maximum walking psychological distance of the city’s citizens, which is 1.5km. Therefore, the system defaults to walking or shared bicycle travel, ignoring other methods and combined travel scheme of the way.

The system separately analyzes the travel costs of walking and shared bicycles. Because of the flexibility of walking and shared bicycles, there is no need to follow a fixed route, so they can travel directly along the shortest route, that is, the shortest path is walking and shared bicycles. The best travel route, so the travel distance of both is 1.2km.

(a) If the travel time is peak hours

For walking trips, the time spent x ₁₁ is:

Then the walking cost is:

For shared bicycle travel, the time spent x ₂₁ is:

Then the cost of shared bicycle travel is:

Therefore, Cost ₂ is smaller than Cost ₁ , that is, the travel cost of shared bicycles is less than the cost of walking travel, so the system recommends the travel plan of shared bicycles to users.

(b) If the travel time is off-peak hours

For walking trips, the time spent x ₁₁ is:

Then the walking cost is:

For shared bicycle travel, the time spent x ₂₁ is:

Then the cost of shared bicycle travel is:

Therefore, Cost ₂ is smaller than Cost ₁ , that is, the travel cost of shared bicycles is less than the cost of walking travel, so the system recommends the travel plan of shared bicycles to users.

(2) It is known that the starting point location and destination location obtained by the traveler using the built-in GPS software of the shared bicycle at 8:30 in the morning (that is, the rush hour) are shown in Figure 4 in the mobile app, try to analyze the built-in system analysis process and determine the optimal travel plan.

According to GPS navigation, the shortest distance from the origin of the trip to the destination is 2.8km, which is 1.5km greater than the optimal psychological distance for walking. The nearest subway station is 1.2km, of which, the length of the conventional bus travel route is 2.2km, the length of the subway travel route is 906 meters, the distance between the final station of the subway and the terminal of the trip is 630m, and the final station of the conventional bus is 540m. The system analysis is as follows:

(a) Shared bicycle trips only:

At this time, the travel time of only using shared bicycles is:

Then the travel cost of this scheme is:

(b) Walk + regular bus:

At this time, the travel time using this scheme is:

x ₃ =x ₁₁ +x ₃₁

Among them, x ₁₁ is the time spent on walking, and x ₃₁ is the time spent on regular bus travel:

x ₁₁ =x _11a +x _11b

Among them, x _11a is the time spent from the initial point to the nearest regular bus stop, and x _11b is the time spent from the regular bus terminal to the departure destination.

x ₁₁ =9.24+7.5=16.74min

Then, the travel cost of this scheme is:

(c) Shared bicycle + regular bus:

At this time, using this plan to travel, the time spent is:

x ₄ =x ₂₁ +x ₃₁

Among them, x ₂₁ is the time spent on shared bicycles, and x ₃₁ is the time spent on regular bus travel:

x ₂₁ =x _21a +x _21b

Among them, x _21a is the time spent from the initial point to the nearest regular bus stop, and x _21b is the time spent from the regular bus terminal to the departure destination.

x ₂₁ =3.78+4.62=8.4min

Then, the travel cost of this scheme is:

(d) walk + subway

At this time, using this plan to travel, the time spent is:

x ₅ =x ₁₁ +x ₄₁

Among them, x ₁₁ is the time spent on walking, and x ₄₁ is the time spent on subway travel:

Then, the travel cost of this scheme is:

(e) Shared bicycle + subway

At this time, using this plan to travel, the time spent is:

x ₆ =x ₂₁ +x ₄₁

Among them, x ₂₁ is the time spent on shared bicycles:

x ₄₁ is the subway travel time, which is the same as the above:

Then, the travel cost of this scheme is:

(f) Walking + regular bus + shared bicycle

x ₇ =x ₁₁ +x ₃₁ +x ₂₁

Among them, x ₁₁ is the time spent on walking, x ₃₁ is the time spent on regular public transportation, and x ₂₁ is the time spent on shared bicycles.

Similarly, the travel cost of this scheme is calculated as

(g) Shared bicycle + conventional bus + walking

Similarly, the travel cost of this scheme is calculated as

(h) walking + subway + shared bicycle

The travel cost of this scheme is

(i) Shared bicycle + subway + walking

The travel cost of this scheme is

Then the costs of all travel plans are shown in Table 1:

Table 1 Comparison of travel costs of different travel plans

In summary, the cost of the whole journey shared bicycle travel mode is the smallest, therefore, the system recommends this travel plan to users.

It should be pointed out that the above-mentioned cases are only examples for clearly explaining, and are not intended to limit the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
