System and methods for quantifying greenhouse gas emissions via measurement and modelling of traffic data and for influencing traffic signaling to reduce such emissions

A method of reducing greenhouse gas (GHG) emissions by influencing traffic signaling and timing, the method comprising:

• determining baseline GHG emissions for traffic in an intersection or network comprising a plurality of intersections;
• updating a signal timing plan or signal control strategy at the intersection or plurality of intersections;
• quantifying GHG emissions for impacted vehicles based on the updated signal timing plan or signal control strategy;
• and
• comparing new GHG emissions to the baseline GHG emissions to compute carbon offset credits.

A system for quantifying greenhouse gas (GHG) emissions associated with vehicle traffic, the system comprising a processor and memory, the memory comprising computer executable instructions that, when executed by the processor, cause the system to:

• receive data from a plurality of devices located at a plurality of traffic intersections in a traffic network, each device comprising at least one sensor configured to obtain data from the corresponding traffic intersection;
• use the received data and a traffic model to determine vehicle trajectory data;
• use the vehicle trajectory data and an emissions model to obtain corresponding GHG emissions data;
• and
• evaluate the corresponding GHG emissions data to a baseline of GHG emissions using a GHG quantification methodology to determine a GHG reduction that can achieve a carbon offset credit.
