Two measures that have been introduced by the US and local governments to reduce the consumption of gas are the introduction of light-rail and the use of carpool lanes.
Explanation:
The introduction of light-rail will reduce the consumption of gas from personal vehicles and also reduce personal vehicle carbon emissions. One example is the Dallas Area Rapid Transit (DART) and Los Angeles has a system that combines light rail and heavy rail called Metro Rail. The use of carpool lanes will reduce the use of gas and help to reduce traffic congestion because there will be less cars on the road in high traffic areas where there is a large percentage of the population who commutes to and from work on freeways. Carpool lanes or High Capacity Vehicle (HCV) lanes are found in metropolitan areas like Washington DC.
