1. An engine control system for a vehicle having an engine, comprising: an engine controller configured to determine an acceptable range for an engine operating parameter responsive to traffic conditions and to direct the engine to maintain the engine operating parameter within the acceptable range,
1. An engine control system for a vehicle having an engine, comprising: an engine controller configured to determine an acceptable range for an engine operating parameter responsive to traffic conditions and to direct the engine to maintain the engine operating parameter within the acceptable range,wherein the engine operating parameter is selected from the group consisting of compression ratio, timing of commencement of fuel combustion, timing of fuel injection, timing of fuel introduction into an air-inlet stream, valve timing, fuel composition, air inlet temperature, air inlet pressure, number of operating cylinders, battery usage, battery charge, engine or drive-train usage of electrical energy, engine operating rate, and output torque; anda compliance reporting unit configured to transmit a record of engine operating adjustments to a remote unit. 2. The engine control system of claim 1, wherein the engine controller is further configured to receive a traffic condition signal from an external source. 3. The engine control system of claim 2, wherein the external source is a central repository of traffic information. 4. The engine control system of claim 2, wherein the external source is another vehicle. 5. The engine control system of claim 1, wherein the engine controller is further configured to monitor vehicle operation in order to determine traffic conditions. 6. A method of controlling a vehicle having an engine, comprising: responsive to traffic conditions, determining an acceptable range for an engine operating parameter and directing the engine to maintain the engine operating parameter within the acceptable range,wherein the engine operating parameter is selected from the group consisting of compression ratio, timing of commencement of fuel combustion, timing of fuel injection, timing of fuel introduction into an air-inlet stream, valve timing, fuel composition, air inlet temperature, air inlet pressure, number of operating cylinders, battery usage, battery charge, engine or drive-train usage of electrical energy, engine operating rate, and output torque; andtransmitting a record of engine operating adjustments to a remote unit. 7. The method of claim 6, further comprising receiving a traffic condition signal from an external source. 8. The method of claim 7, wherein the external source is a central repository of traffic information. 9. The method of claim 7, wherein the external source is another vehicle. 10. The method of claim 6, further comprising monitoring vehicle operation in order to determine traffic conditions. 11. The engine control system of claim 1, wherein the compliance reporting unit is configured to transmit during engine operation. 12. The engine control system of claim 1, wherein the compliance reporting unit is configured to store a record of engine parameter values for later transmission. 13. The method of claim 6, wherein transmitting a record includes transmitting during engine operation. 14. The method of claim 6, wherein transmitting a record includes storing the record and subsequently transmitting it. 15. An engine control system for a vehicle having an engine, comprising: an engine controller configured to determine an acceptable range for an engine operating parameter responsive to traffic conditions and to a sensed exhaust parameter; anddirect the engine to maintain the engine operating parameter within the acceptable range,wherein the engine operating parameter is selected from the group consisting of compression ratio, timing of commencement of fuel combustion, timing of fuel injection, timing of fuel introduction into an air-inlet stream, valve timing, fuel composition, air inlet temperature, air inlet pressure, number of operating cylinders, battery usage, battery charge, engine or drive-train usage of electrical energy, engine operating rate, and output torque, andwherein the exhaust parameter is selected from the group consisting of exhaust gas temperature, exhaust gas temperature profile, exhaust gas composition, exhaust gas back pressure, catalytic converter reactive area, exhaust gas flow path, catalyst selection, sequestration of at least one exhaust gas component, exhaust gas flow rate, exhaust particulates density, exhaust particulate composition, exhaust particulate size, concentration of exhaust components at a selected location in an exhaust flow path, coolant temperature, and inlet-exhaust thermal coupling. 16. A method of controlling a vehicle having an engine, comprising: responsive to traffic conditions and to a sensed exhaust parameter, determining an acceptable range for an engine operating parameter and directing the engine to maintain the engine operating parameter within the acceptable range,wherein the engine operating parameter is selected from the group consisting of compression ratio, timing of commencement of fuel combustion, timing of fuel injection, timing of fuel introduction into an air-inlet stream, valve timing, fuel composition, air inlet temperature, air inlet pressure, number of operating cylinders, battery usage, battery charge, engine or drive-train usage of electrical energy, engine operating rate, and output torque, andwherein the exhaust parameter is selected from the group consisting of exhaust gas temperature, exhaust gas temperature profile, exhaust gas composition, exhaust gas back pressure, catalytic converter reactive area, exhaust gas flow path, catalyst selection, sequestration of at least one exhaust gas component, exhaust gas flow rate, exhaust particulates density, exhaust particulate composition, exhaust particulate size, concentration of exhaust components at a selected location in an exhaust flow path, coolant temperature, and inlet-exhaust thermal coupling.
