Intelligent Transportation Systems

Growing concerns over global motorization and climate change have led to increasing interest in sustainable transportation alternatives, such as bikesharing (the shared use of a bicycle fleet). Since 1965, bikesharing has grown across the globe on four continents including: Europe, North America, South America, and Asia (including Australia). Today, there are approximately 100 bikesharing programs operating in an estimated 125 cities around the world with over 139,300 bicycles. Bikesharing’s evolution is categorized into three generations: 1) White Bikes (or Free Bike Systems); 2) Coin-...

Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.Fortunately...

The Program on Advanced Technology for the Highway (PATH), has been established in response to funding by the United States Congress and the California Legislature to demonstrate how "high technology" might be applied to improve highway transportation. PATH's goal, in the short run, is to implement technologies which promise significant relief of acute problemsincluding traffic congestion, air pollution and energy use. Alternative systems of vehicle guidance and control, navigation, propulsion, and communication will be studied and/or developed. The impacts of these systems on highway...

This paper describes the specifications and the determinants for inclusion of a deliberative process to support intelligent transportation planning. Specifications for a system suitable for transportation planning have been defined, as have the determinants of a prototype for inclusion in early versions of an intelligent transportation planning process. The PLANiTS ( Planning and Analysis to Integrate Intelligent Urban Transportation Systems) framework is utilized in this project.
