The 'Avoid, Shift, Improve' or ASI approach is a three-step approach to greening public transport systems which can be used by governments, local authorities and urban planners. The first 'Avoid' step involves considering how travel can be altogether avoided, such as through the use of greater remote working, and shortening the distances between homes and the services that individuals will require as part of urban planning. The 'Shift' step is a focus on moving to less-emitting modes of transport, encouraging active mobility like walking and cycling, and greater use of public transport networks. Urban planners and government policy should ensure that infrastructure is enabling to encourage individuals to use these greener modes of transport. Finally, the 'Improve' aspect of the framework involves improving the technology of vehicles so that they are less polluting. This can involve use of hybrid, electric, biomass or hydrogen fuelled vehicles in the public transport system, as well as for private use. Considerations such as greater automation of transport, and predicted maintenance services are examples of how technology can be harnessed in this final step in order to ensure that transport systems remain efficient and reliable.
