Description

Technical Field

[0001] The present invention relates to the field of urban transportation, and in particular to an intelligent rapid transportation method and system. Background Art

[0002] Intelligent Transportation System (ITS) is a comprehensive transportation and management system that is established by effectively integrating advanced information technology, communication technology, sensor technology, control technology and computer technology and applying them to the entire transportation management system, and plays a role in a wide range and in all aspects, in real time, accurately and efficiently.

[0003] Most of the existing intelligent transportation systems are personal rapid transit systems (PRT), also known as personal rapid transit systems, or personal rapid transit for short. It is an automated small-capacity transportation system consisting of small vehicles and their dedicated running routes, providing point-to-point transportation for passengers.

[0004] There are the following disadvantages:

[0005] 1. The transport capacity is small, and each vehicle can carry a maximum of 6 people.

[0006] 2. Low speed, the maximum speed is only 40km / h.

[0007] 3. The form is single, and the only type of vehicle in operation is PRT.

[0008] 4. The application scope is narrow. Due to its small capacity and low speed, its current application cannot be popularized. It is generally used as a connecting line between airports and parking buildings. Summary of the invention

[0011] Large vehicles operate in a bus-like mode, running across stations or not according to the characteristics of passenger flow;

[0012] Small vehicles operate in automatic response mode, receive travel plans from smart terminals, and use the departure intervals of large vehicles to provide point-to-point direct transportation.

[0013] In an optional scheme of the intelligent rapid transportation method, vehicles are dynamically virtually grouped, and the number of vehicles in the group is determined according to the passenger flow. During the virtual grouping of vehicles, the vehicles are virtually coupled through a control center and vehicle-to-vehicle communications, and the virtually coupled vehicles have consistent driving speeds, accelerations, and decelerations.

The control center communicates with the large vehicles and the small vehicles, and the vehicles communicate with each other, including large vehicles and large vehicles, small vehicles and small vehicles, and large vehicles and small vehicles. The intelligent terminal communicates with the control center; large vehicles and small vehicles are mixed and compatible on a shared line. The running line can be an elevated line, a ground line, an underground line, or any combination thereof according to external conditions, and is designed according to the actual situation of the project. The two-way limit width in the running line is preferably, but not limited to, 5.6 meters, the height is preferably, but not limited to, 2.6 meters, the minimum turning radius is preferably, but not limited to, 8 meters, and the maximum climbing grade is 13%. It can be in various forms such as elevated, ground, and underground, with strong adaptability. The roadbed, bridge, and tunnel engineering can save 27%, 31%, and 58% respectively compared with general roads (two-lane roads). The control center dispatches large and small vehicles, including:

[0030] Driving organization:

[0031] The control center controls large vehicles to operate in a public transportation mode, and they may or may not operate across stations according to the characteristics of passenger flow. For specific implementation, please refer to the bus call bell. For the upcoming station, the passengers who get off the bus will ring the bell to call. If there is a demand, the vehicle will enter the station and stop. If there is no call, the vehicle will pass directly.

[0032] The control center controls the small car to operate in automatic response mode. The small car receives the travel plan from the smart terminal and uses the departure intervals of the large car to carry out point-to-point direct transportation.

[0033] Calculation method of small car scale: Based on the passenger turnover of small cars on the entire line during peak hours Q s (Terminal front-end input data, known data), small car vehicle utilization efficiency w s ,; Small car capacity P s , the average full load rate of small cars K s , the average travel speed of small cars V s , small vehicle operation turnover time t s , calculate the maximum number of small cars released during peak hours C s , the calculation formula is as follows:

[0034]

[0035] Where: Q S — passenger turnover of small cars on the entire line during peak hours (person*km / h); P S —The number of passengers in a small car (person / car). In this embodiment, the small car can carry 6 passengers. ; KS —Average full load factor of small cars; V S —average travel speed of a small car (km / h), in this embodiment, the maximum speed is 60-80 km / h; t S —Small vehicle operation turnaround time; w S —Vehicle utilization efficiency.

[0036] Large vehicle size calculation method: Based on the average travel speed V of large vehicles B , total round trip distance L B , the number of public transportation passengers on the entire line during peak hours Q B , Large vehicle capacity P B In this embodiment, the large vehicle carries 22 passengers, and the average full load rate of the large vehicle is K B , calculate the maximum number of large vehicles deployed during peak hours C B , the calculation formula is as follows:

[0037]

[0038] Where: Q B —The number of public transportation passengers on the entire line during peak hours (persons / h), which can be calculated by predicting passenger flow; L S —Total round trip distance (km); P B —Number of people per vehicle for large vehicles; K B —Average full load factor of large vehicles; V B - Average travel speed of large vehicles (km / h). In this embodiment, the maximum speed is 60-80 km / h.

[0039] During off-peak hours, large vehicles are dispatched in real time based on passenger arrival conditions to reduce operating costs and ensure operational quality.

[0040] Calculation method for the number of parking spaces for small vehicles: Based on the time t that small vehicles are allowed to enter the parking spaces and park steadily 入 , the time from when the parking space is cleared to when the next small car is allowed to enter the parking space is t 出 , stop time t 停 , the efficiency discount coefficient J caused by objective reasons, calculate the total number of parking spaces N for small vehicles at the station, and the calculation formula is as follows:

[0041]

[0042] Where: n—parking demand of small cars in peak hours; t 入 —The time interval from when a vehicle is allowed to enter a parking space to when it stops in the parking space (s); t 出 —The time interval from when a vehicle is allowed to leave the parking space to when the next vehicle is allowed to enter the parking space (s); t 停—The time the vehicle stays at the berth (s); J—Conversion coefficient, delay or advance due to objective reasons.

[0043] Dynamic scheduling method for vehicle marshaling: Dynamic virtual marshaling of vehicles. The number of vehicles in the marshaling is determined according to the number of passenger flows. During the process of virtual marshaling of vehicles, the vehicles are virtually coupled through the control center and vehicle-to-vehicle communication. The driving speed, acceleration and deceleration of the virtually coupled vehicles are consistent. Usually, during the off-peak period of passenger flow, the vehicle transport capacity meets the passenger flow needs and there is no need for marshaling. During the peak period of passenger flow, the vehicles are dynamically virtually marshaled to increase the system transport capacity. The principle of dynamic virtual marshaling is: vehicles that are close to each other are marshaled through speed coordination, large vehicles are marshaled with large vehicles, small vehicles are marshaled with small vehicles, and large and small vehicles are not mixed.
