Research and Implementation of Intelligent taxi-dispatching
Client Based on Android Platform
Abstract
In the context of social development, taxi as urban residents’ convenient way for
daily short-distance moving, has been getting rapid development. Formerly the access
to taxi mainly depended on waving hands at the side of the road to taxi drivers passing
by, which was assisted by telephone dispatching as supplement. But this hand-waving
way is of irregularity and unpredictability and telephone dispatching platform is not
popular in small and medium-sized cities due to its cost price and limited technology,
which leads to high rate of empty taxi on road, especially when drivers are on the way
to shift duties. As a result, it increases the drivers’ operating cost and reduces the
effective capacity of the taxi. At the same time, with the constant growing of mobile
internet and intelligent terminal market in recent years, taxi dispatching application
software based on mobile intelligent terminals emerged at the right time. Although it
provides a direction to solve the problem, its design doesn’t take drivers’ behavioral
habit and operating environment into full consideration, and there are several
functional deficiencies such as reminding of unfinished orders, systematic real-time
announcement show. On the basis of a thorough investigation into the drivers’ actual
demands, this paper put forward an intelligent taxi-dispatching system based on
Android terminal to solve the above problems.
This paper starts with introducing the development situations in related fields at
home and abroad, and points out the challenge and broad market prospect of the taxi
dispatching mobile software. Then it presents the related technologies to implement
the present system, which is followed by detailed descriptions of users’ demand
analysis, the framework of the system and the module division of client. This paper
further analyzes the key technical problems in the process of software development
and puts forwards feasible solutions. In the end, each module’s design and realization
of the system are described with details.
To realize the system, this paper also made the following research. 1.the research
on the algorithm of GPS data collection and uploading, and raises the solution of
uploading GPS data based on the variations of distance and time. 2.the author studied
the color collocation of user interface and font in the system, and summarized the
