In a broad sense, GIS is a system consisting various location enabled services. Among the various potential applications, GIS can be used for; nowadays transportation issues have received a lot of attention. It is specially called GIS-T. Geographic Information System for Transportation refers to principles of applying GIS technique for transportation purposes like routing, traffic jam problems. It is necessary for a successful business that right person is present at the right place at the right time. Each corporation’s need varies. This includes personal travel as well as shipping of raw materials and products.
Developing Countries like India that is urbanizing at a rapid pace. GIS has become mainstream. GIS creates transportation system sustainable in terms of increasing social inclusion, reducing environmental limitations and being economically feasible. This helps public transportation giving information about infrastructure and urban design. Like GIS represents the street network as center-lines which is helpful for transportation facility and vehicle routing application. Different applications need different information and analyzing. GIS-T allows multiple geometric representations of the same transportation network. GIS is an attractive choice for logistic providers.
The use of this software is still not common in many of the companies. GIS helps in gathering useful information for the multinational companies, what is done at each location. This is done by merging data from geographic content such as maps, images, applications and other geographic information commonly used for planning, deploying, operating and optimizing transportation and logistical systems. Safety can also be ensured by GIS. Many businesses involve operations that need GIS, and some of them are supplier sites, distribution centers, retail stores, and customer location. It allows taking decisions regarding the economic route selection.
Use of GIS in transportation applications is too wide. Complex applications include highway maintenance, traffic modeling, and accident analysis. GIS gives the info according to latitude and longitude of a place. It gives info which is reliable, updated, relevant, easily accessible and affordable. GIS is getting better as today existing database does not allow the viewer to access or query the database while the user is only allowed to raise textual queries. Furthermore, GIS ability cannot be doubted.
