The present invention discloses a server for travel-time estimation capable of:

• Receiving Travel Information: received from a user device specifies a particular route for which travel time needs to be estimated.
• Receiving Traffic Data: Server receives traffic data multiple receiver modules distributed along the route.
• Classify and re-identify the vehicles: Based on the traffic data the vehicles are classified and re-identified
• Determine a travel-time interval for the route:Using the traffic data and the travel information, the server calculates a travel-time interval for the specified route.
• Communicating the travel time: The server then communicates this calculated travel-time interval to the user device, which requested the travel-time estimation.

The traffic data received from the server includes two types of information:

• identification information associated with computing devices in the traffic streams vehicle information associated with the vehicles in those streams
• The said  receiver module comprises:
•  a Wi-Fi Media Access Control Scanner (WMS) for determining identification information associated with computing devices in the traffic stream; and
• a Light Detection and Ranging (LIDAR) system for determining vehicle information associated with vehicles in the traffic stream.
• The travel time interval determined both an upper bound and a lower bound, providing a range of estimated travel times.
• The server further obtain historical data associated with the route, wherein the historical data indicates past traffic information for one of the route and a transportation network; and determine the travel-time interval for the route, based on the historical data, the travel information and the traffic data from the at least one receiver module.
