Transportation diversity refers to the variety of mobility and accessibility options available in a particular situation, including various modes, services and destinations. A transport system must be diverse in order to serve diverse demands, including the needs of people who cannot, should not or prefer not to drive. Multimodal planning that increases transport system diversity tends to increase efficiency, equity and resilience, and achieve various planning goals including congestion reduction, infrastructure savings, affordability, improved mobility for non-drivers, traffic safety, increased public fitness and health, environmental protection and support for strategic development objectives.
