Description

Method and system for dispatching taxis

technical field

The invention relates to the field of mobile application services, in particular to a taxi dispatching method and system.

Background technique

With the development of economy, taxis have increasingly become an important part of the urban transportation system due to their convenience, speed, safety and comfort. The traditional taxi dispatching system generally consists of three parts: vehicle terminal, call center, and taxi dispatching platform. When passengers need a taxi, they first call the taxi service hotline of the call center, and the seat service personnel of the call center provide reception, record the contact information of the car-hailing personnel and the place where the taxi is taken, and then forward it to the taxi dispatching platform. The taxi dispatching platform broadcasts the contracted car record to all taxi terminals in the company's public frequency band in the form of voice messages, and the taxi driver will directly contact the passenger according to the passenger's contact information in the car-hailing record.

There are following defects in this taxi dispatching method:

The call center needs to maintain a certain number of service personnel, which increases the operating cost of the taxi company; and the number of service personnel is limited, and the service personnel are often fully busy during the peak hours of calling a taxi, which increases the waiting time of passengers;

The car-hailing record is generated through the communication between the passenger and the service personnel of the call center, which may cause errors in the record of the car-hailing information due to the influence of the passenger’s dialect; or, the passengers are not familiar with their surrounding environment, resulting in inaccurate boarding locations provided to the service personnel;

Car-hailing service hotlines often implement their own charging standards, and passengers need to bear the basic call charges and high hotline service fees;

Passengers’ car-hailing information is broadcast in the company’s public communication frequency band, which is poorly targeted. For taxis driving in areas far away from passengers, or taxis that have already loaded passengers, invalid voice broadcast information is no different than a noise;

The use of mobile phones by drivers to communicate with passengers during driving is a safety hazard during driving. Now major cities have begun to explicitly prohibit the use of mobile phones while driving;

The call center has no ability to identify and restrict malicious and false car-hailing calls, resulting in waste of vehicle dispatch and a decrease in trust between passengers and taxi drivers.

With the popularization of smart phones, APP application software that helps passengers to call a car through the mobile Internet has begun to appear on the market. Similar to the traditional phone call service, passengers send a call by clicking the "I want to use a car" software installed on their mobile phones. Request, and send a voice to explain the location of the car and the place to go; the car information will be sent by the server to the mobile phone of the taxi driver who has installed the corresponding car answering software near the passenger, and the taxi driver will respond with one click , and contact the passenger. This method does not require seat service personnel, and can accept a large number of passenger requests for taxis at the same time, and the taxi information is only sent to the taxis near the passengers, which is a significant improvement over the traditional way of calling taxis by telephone. However, this way of calling a car requires the passenger’s mobile phone to turn on the positioning service to report their own location, which consumes a lot of battery power of the mobile phone, and because the location of the car is provided by the passenger’s voice, it is still unavoidable due to the influence of the passenger’s dialect, or the passenger is not familiar with the surrounding environment. And the taxi driver can't accurately obtain the problem of car-hailing location.
