CrowdMap

Challenges

Multiple challenges had to be tackled to develop CrowdMap. We list here the major ones;

• Developing an intelligent data logging system
• Automatically sense route signatures or landmarks like speed breakers, turns, etc
• Generate the complete trajectory of the bus using only inertial sensor data
• Discover a unique bus route on the map

Contributions

We propose a crowdsource based solution, CrowdMap that tackles the problems discussed earlier. CrowdMap seamlessly discovers the bus routes, and embeds the annotated route information on the city map. The major contributions of CrowdMap are;

• A data collection module that uniquely identifies the user is in a bus and logs required data.
• Detects and tags landmarks
• Generates a trajectory of the route travelled by the user
• Annotate bus routes on map alongwith comfort level information
