Assembly Bill (AB) 32: Global Warming Solutions Act: Transportation Sector White Papers & Stakeholder Workshops

Growing consciousness about global warming is prompting increased action at the local and state levels. Transportation technologies and strategies are emerging that can help to meet the climate challenge, including automotive and fuels technologies, intelligent transportation systems (ITS), and mobility and land use management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility and land use management strategies. In the future, ITS, mobility management, and smart growth will likely play a greater role in reducing fuel consumption.

Smart Parking

“Smart Parking” employs various types of advanced parking systems and technologies to assist drivers in finding available parking spaces.  IMR’s approach to smart parking management is to apply advanced technologies to help direct drivers efficiently to available parking spaces, reducing driver frustration and congestion on highways and arterial streets. 

Smart parking approaches range from dynamic displays on roadway signs informing drivers of location and parking lot capacity, to use of the Internet and cell phones to provide space availability, location, and pricing information.  Additionally, advanced payment systems allow for seamless parking transactions and enhanced efficiency.  Smart parking can make better use of existing parking infrastructure by creating market-based systems to improve utilization rates and manage vehicle turnover.

Parking availability influences how individuals commute, which, in turn, impacts transit use, single occupancy vehicle driving, and traffic congestion.  Through its research and projects, IMR seeks to create a greater understanding of the impacts of smart parking strategies on the broader transportation system, including how it affects people’s decisions to choose a particular mode of transportation over others.

Access from transit stations to employment and home locations can be a significant barrier to transit use in many urban regions, which is also commonly known as the “first and last mile” problem. Most people are only willing to walk about a quarter of a mile from transit stations to their destination. Bus feeder services can increase access, but fixed routes and schedules significantly limit their appeal. EasyConnect project researches  effective demand-responsive, easy-to-use system that links home, work, and other activity destinations with transit stations may encourage greater transit use, reduce vehicle travel, and emissions.

Carlink I and Carlink II Research Projects

CarLink I and II were commuter-based carsharing research programs led by Dr. Susan Shaheen, who has evaluated and studied carsharing since the concept first gained foothold in North America. CarLink I and II were among the first innovative carsharing projects tested in North America.

Smart Growth, Transit Investment, and Travel Pricing


IMR has conducted extensive research into issues surrounding alternative land use and transport futures.  Past research has included: smart growth, investment, and travel pricing; carsharing and carfree housing; advanced transit and highways; and the Smart Mobility Model project.
