Embodiment Construction

[0064] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0065] Such as figure 1 As shown, the taxi index description system using domain specific language consists of language design module, language analysis module and index calculation module.

[0066] The language design module is designed to sort out, abstract and encapsulate the indicators of taxi operation management, establish an indicator system, and form an indicator description language. The description language is divided into statement statements and calculation statements. Statement statements are used to describe indicators, and calculation statements Completion of calculations. According to the characteristic requirements of taxi analysis, the index system is designed into five categories: mileage index, time index, speed index, OD index and space-time distribution index, and the data involved in index description and calculation are divide...

Abstract

The invention relates to a taxi supervision-oriented domain-specific language description system and a method. The system comprises a language design module, a language analysis module and an index calculation module. For the index analysis work in the taxi supervision field, the redundancy of codes is avoided and the expandability of indexes is increased. The code work of field experts is avoidedand the convenience is provided for analysis work. The system can be used as a medium between field experts and code people. The time for communication between field experts and code people by usingdifficult-to-understand languages can be reduced. An authenticated, unambiguous, clear and accurate language is used for communication, and the generation of ambiguity can be avoided as much as possible.

Description

technical field [0001] The invention relates to a domain-specific language description system and method for taxi supervision, belonging to the technical field of data analysis. Background technique [0002] At present, the number of cars in cities is gradually increasing, and the demand for travel is increasing. There are certain congestion problems in the traffic of many cities. Vigorously developing public transportation is an important way to meet the travel needs of citizens. As a part of public transportation, taxis play an important role in people's travel. accounted for a large proportion, but the empty rate of taxis is still at a relatively high level. [0003] According to statistics, the number of motor vehicles in Beijing at the end of 2012 was 5.2 million, a net increase of 216,000 compared with the end of 2011, and the average daily trips within the Sixth Ring Road reached 30.33 million (excluding walking), an increase of 160 compared with the end of 2011. 10,...
