One definition of sustainable mobility is that used by the World Business Council for Sustainable Development as part of that organization’s Mobility Project 2030:
...mobility that meets the needs of society to move freely, gain access, communicate, trade and establish relationships without sacrificing other essential human or ecological requirements today or in the future.
There is a need to unpack this definition in order to identify appropriate transport planning strategies. This can be done by establishing a set of principles that provide a framework for policy goals that will change over time, in response to the changing status quo and political priorities. The strategies derived from these principles would not only be about the modes people are using, nor only about transportation. They would require a multi-sector, inclusive approach to planning.
I suggest the following principles:
1. Preserve the natural environment
The environment should not be degraded by transport-related activity.
2. Maintain human health and safety
Transport systems can have a direct impact on health and safety.
3. Meet the travel needs of the population
People need reliability and choice of modes in an integrated system that provides for those of all abilities and financial means.
4. Support a good economy
Transport needs to support an economy that improves the well-being of all people, with due regard to social equity.
5. Minimize transport costs for access and mobility
Reducing the cost of mobility and access will improve the ability of transport-disadvantaged people to make use of available social, cultural and economic opportunities.
6. Minimize infrastructure costs
Transport systems need to be planned in a manner that their infrastructure and services can be funded in the long term, and that best use is made of investments.
7. Maintain energy security
Transport can play a significant role in helping to decouple support of a good economy from increasing demand for fossil fuels.
8. Ensure long-term viability of the transport system
Transport infrastructure and services need to be continuously maintained; and as an integrated system, all components must work together for optimum effectiveness.
