Use of spatially referenced data

Selective spatial and attribute query

Influencing factors:
There are certain parameters which need to be considered for performing the analysis. Weightages are assigned to each of the parameters based on the existing situation and the requirement of the public. They are arranged according to their of degree of importance as

1. Maximum & minimum distance between two successive point locations:
2. Importance of location
3. Density of population
4. Time
5. Availability of infrastructure and finance
6. Willingness to walk
7. Monetary status of the people
8. Site details such as junction points etc.

The maximum distance between two stops is taken to be not more than 2 kilometers, this distance is assigned based on the type of settlement, the study of the landuse pattern gives an understanding about the population, population density and the monetary status. The present study is based mostly on ground data with some amount of sampling and then the data is extended through interpolation technique. The minimum distance is taken as 500 meters.

The above mentioned norms are adhered to as long there are no other forceful factors such as the presence of any imperative location such as hospitals which cannot be ignored. These are vital locations for locating bus stops irrespective of the separable distance between them as they serve the needy who cannot afford other modes of transport. The other important locational data considered are the schools, temples, colleges and other important tourist location.

Willingness to walk is another important criteria which is the underlying factor for making the decision on the distance. In certain cases there may be willingness to walk little extra distance in return for pollution free environment. In these conditions the bus stops are not located in the interior regio
