Variable rate transport fees based on vehicle exhaust emissions

A system for reducing levels of harmful exhaust emissions from motor vehicles, comprising:

• a sensor to measure vehicle exhaust emissions;
• an analyzer for determining levels of pollutants in the exhaust emissions;
• a transmitter for forwarding exhaust emission information to a fee assessor;
• and
• a fee calculator for determining an amount of a vehicle use fee based on the level of pollution in said exhaust emissions.

In a computer system, a computer program, comprising:

• a computer-readable medium;
• and
• a computer executable program code stored on the computer-readable medium, the program code capable of being deployed by the system to:
• obtain vehicle exhaust emission information from an emission sensor;
• quantify the level of pollution in exhaust emission;
• and
• transmit information relating to the pollution levels to a vehicle fee collection agency responsible for the collection of a fee based on the level of pollution.

A method, comprising:

• producing computer executable program code;
• storing the code on a computer readable medium;
• and
• executing the program code on a computer system, the program code comprising instructions which, when executed on the computer system, cause the computer system to:
• obtain vehicle exhaust emission information from an exhaust emission sensor;
• quantify a level of pollution in the exhaust emissions;
• transmit information relating to the pollution level to a fee collection agency;
• and
• assess a vehicle user fee based on the level of pollution in said exhaust emissions.

A method of providing a service of:

• collecting exhaust emission information from a vehicle in operation;
• quantifying a level of pollution in the exhaust emissions of said vehicle;
• and
• assessing a user-based fee on the vehicle based on the level of pollution in said exhaust emissions.
