Real-time emissions estimation and monitoring

A transportation mobility system, comprising:

• a data storage configured to maintain vehicle data indicating fuel consumption and count of passengers for vehicles of a transportation system, and user data describing movements of the passengers within the transportation system;
• and
• an emissions monitoring portal, programmed to
• estimate a level of traffic congestion for a road segment traversed by one of the vehicles,
• calculate a proportion of vehicles on the road segment from which vehicle data is being periodically received to the data storage,
• if the proportion exceeds a predefined threshold value, calculate a marginal cost of an additional vehicle traversing the road segment according to the level of traffic congestion,
• otherwise, estimate a social cost for vehicle traversal of the road segment based on average fuel economy of vehicles along the road segment, and
• provide, for the vehicles of a fleet, estimates of pollutant emissions for the fleet according to the estimates and calculations.

A method for estimation of emissions resulting from use of vehicles comprising:

• receiving, from vehicles of a transportation system, vehicle data indicating fuel consumption and count of passengers for the vehicles;
• receiving, from mobile devices of passengers, user data describing movements of the passengers within the transportation system;
• allocating revenue emissions of the vehicles to the passengers according to the fuel consumption divided by the count of passengers when the passenger was a rider, and allocate deadhead emissions to the passengers divided by a total number of passengers during a vehicle service period;
• and
• one or more of:
• including, in the allocating of emissions, well-to-tank emissions for the vehicles accounting for emissions associated with production of the fuel and tank-to-wheels emissions computed by the vehicle according the vehicle emissions measurements, or
• receiving emissions profile information from the vehicles for computation of well-to-tank emissions, the emissions profile information being one or more of captured from refueling infrastructure providing fuel to the vehicles or estimated according to local utility information specifying an efficiency of local energy generation.
