Sustainability

This paper explores the implications of “global warming” induced climate change on various aspects of transportation planning. It takes primarily a view which assumes the predictions become manifest and how today’s planner might look at today’s long-term transportation investments and policies. It also explores possibilities for using existing information systems tolls to expand current planning methods in order to consider Climate Changes in the planning process.

A critical trip generation rate or population density in cities above which traffic congestion
would be induced is derived. When the trip rate in a city exceeds the critical number, traffic
congestion prevails. The effects of employing an intelligent transit system to mitigate traffic
congestion and vehicle emissions are estimated based on an analytic framework. The benefits
attained by employing the intelligent transit in gasoline consumption and reduction in trip
time are estimated on an annual basis. The benefits are further demonstrated using a city like
Sacramento of California. The model is of great practical importance when applied to match
with transportation and urban development planning processes prepared by government
agencies at various levels.

Based on the discussion of the meaning of ITS concept, the importance and necessity of ITS
education and training on ITS sustainable development are expounded first. Then combined
with Chinese characteristics, the targets of ITS education are summarized, i.e. research
institutes, ITS-related industries and transport agencies. Finally, the approaches to building
ITS capability are put forward, including formal education and continuing education.

Since public transport deregulation in the UK the provision of solutions to transport demand
in areas of dispersed demand has been met by local authorities’ attempts to “fill gaps” in the
commercial public transport network, whilst the voluntary sector has addressed the needs of
more specialised travel. Since 2001 more innovative solutions have been enabled by the
development of Intelligent Transport Systems (ITS), which allow more flexible transport
services in terms of time and space. In addition, new ways of thinking about the provision of
what might be considered public transport has led to more flexible transport modes becoming
available, permitting the general public on education contract services, the use of taxis for
shared public transport and the provision of vehicles enabling access to work. However, these
innovations tend to operate independently leading to overlap, gaps and misunderstandings
about the purpose, delivery and receipt of services. To address these issues, future public
transport services will need wider area network planning, greater co-operation between
service providers and improved understanding of passenger requirements. The
Northumberland case study illustrates diverse solutions that have been made to address these
challenges and the key role of ITS in this process.

The evolution of Intelligent Transportation Systems (ITS) has resulted in improved traffic management techniques, public transportation improvements, advanced information technologies, driver aids, and vehicle safety enhancements. However, an often overlooked aspect of ITS operations is the environmental impacts of managing a modern transportation system. Thus, this paper will take a closer look at ITS-related environmental impacts and how ITS can play a greater role in future environmental improvements. With this in mind, this paper will explore the environmental uses of data harvested via existing ITS deployments, and future deployments of Connected Vehicle technologies. This paper will summarize the research behind the SwRI demonstrations of environmental technologies at the ITS World Congress.
