3.1 Results
When ever the user runs this module, it will open a dialog box containing blank spaces to enter the details of the vehicle like height, width and weather weight is more than bridge capacity or not etc. After entering these values, it will show the messages indicating the details entered. Then it will prompt the user to select his origin and destination with a click of a mouse and immediately it will generate the path satisfying all the requirements. If there is no path satisfying the requirements, a message was given by indicating the same. The final results are shown in Figure 3.2 and 3.3. In Figure 3.2 the programme was asked to give a path across a flyover. It generated a path as shown by satisfying all the requirements. In Figure 3.3 a path between Thane and Sewri was asked for a 5 m width vehicle having problems with weight and clearances. The path generated by programme was logical as it is avoiding enroute bridges and minor routes.
