Suggestive improvements in navigation system
- 1. Suggestive Improvements in Navigation System By: Dhawal Singhal
- 2. Intro A frequent user of Google Maps or Navigation must have noticed the ratings given to famous public places like multiplexes, cinemas, shopping malls, etc., by the people after having some experience with the respective places. Dhawal Singhal, December 2014 2
- 3. Main Idea Using the same concept, we can develop a rating system for the routes depending on how frequently people take them. This will help the user choose a better of the many available routes presented by the navigator for a particular destination. Dhawal Singhal, December 2014 3
- 4. Why ? Many times, especially in countries with densely populated areas and asymmetric road network, like India, the routes suggested by the google maps may point to a entirely different location (or seems so, due to inaccuracy), or the path suggested is a high-traffic path. So, the rating given to the routes(or particular roads) can help the users in planning their route. Dhawal Singhal, December 2014 4
- 5. Example Let us understand it with a practical example. During the travel from Chandpur (Dist. Bijnor) to Delhi via Gajraula, the traveler generally has to take a path as indicated in the next slide. Dhawal Singhal, December 2014 5
- 6. A Typical Route Dhawal Singhal, December 2014 6
- 7. In the map, we notice that the path highlighted in red would be the ideal suggestion in the Google Navigation application, given the source being “Chandpur-Gajraula Road” and Delhi being destination. But, taking the real time situation of the place, the middle part (after first right turn) of the route is not operational for about an year due to construction of a flyover enroute. So, we must follow an alternate route as shown in the next slide. Dhawal Singhal, December 2014 7
- 8. Revised Route Dhawal Singhal, December 2014 8
- 9. We can notice that we need to take an alternate route that is in a very different direction specially for someone who is new to the route. Furthermore, there are no proper sign boards on the road to assist the passersby to take that (revised) route. As a result, the navigation user faces difficulties and becomes bound to ask local people for guidance, failing the main objective of google navigation. Dhawal Singhal, December 2014 9
- 10. Implementation The ratings can be given by the users in the same way as they rate other public places. The rating can be based on the traffic conditions, road conditions (major aspect in cities of India), and on their personal experience and/or preference. Dhawal Singhal, December 2014 10
- 11. Implementation The ratings can also be generated by the application by tracking the routes people take most frequently, and a percentage figure can be used to show the general preference of taking a particular path. Dhawal Singhal, December 2014 11
- 12. Stuck!! A “Stuck!!” option can be implemented for the situations where the user find himself stuck or unable to reach their destination by the path suggested by the Navigation tool. Considering the situation mentioned earlier, regarding the blockage of any road due to constructions or other reasons, the user can click on a “Stuck!!” button in navigation tool. Dhawal Singhal, December 2014 12
- 13. Stuck!! This “Stuck!!” generates a signal that there is something wrong with the proposed route, and the navigation tool can suggest an alternate path from that current location. Dhawal Singhal, December 2014 13
- 14. Navigation tool can keep a track of these “stuck” messages and suggest the modified routes accordingly. Further, if the previously blocked road is cleared or a new route is made available, then the users will automatically give a better rating to that route than they were using previously, hence, helping the future users to select the better path.
