Cycling for transportation has become an increasingly important component of strategies to address public health, climate change, and air quality concerns in urban centers. Within this context, planners and policy makers would benefit from an improved understanding of available interventions and their relative effectiveness for cycling promotion. We examined predictors of bicycle commuting that are relevant to planning and policy intervention, particularly those amenable to short- and medium-term action. We estimated a travel mode choice model using data from a...

Reduce Emissions and Improve Traffic Flow Through Collaborative Autonomy

Patire, Anthony D. PhD
Dion, Francis PhD
Bayen, Alexandre M., PhD
2024

This report explores opportunities for employing autonomous driving technology to dampen stop-and-go waves on freeways. If successful, it could reduce fuel consumption and emissions. This technology was tested in an on-road experiment with 100 vehicles over one week. Public stakeholders were engaged to assess the planning effort and feasibility of taking the technology to the next level: a pilot involving 1000+ vehicles over several months. Considerations included the possible geographical boundaries, target fleets of vehicles, and suitable facilities such as bridges or managed lanes. Flow...

Control Strategies For Transit Priority

Skabardonis, Alexander
1998

This report discusses the major factors which influence the benefits from transit priority. It reviews existing control strategies that have been implemented in signal controlled networks. A number of control strategies to improve transit performance are proposed along with an analysis technique to evaluate their effectiveness. The strategies were tested on a major arterial. Recommendations are given, based on the results.

National Evidence Regarding Behavior and Physical Activity in New Urbanist Neighborhoods

Rodriguez, D
Combs, T
McDonald, N
Schlossberg, MA
Greene, J
Larco, N
2012

Although proponents have emphasized new urbanism’s ability to reduce automobile dependence, increase walking, and improve the health of its residents, there is a paucity of research to support these claims. The authors surveyed residents of 34 neighborhoods in 12 U.S. states to examine whether the travel behavior and physical activity of new urbanist neighborhood residents differed from their conventional suburban counterparts. They used a matched-pair design in which each new urbanist neighborhood was matched with a conventional suburban neighborhood in the same municipality....

Regional Intelligent Transportation Systems Architectures and the Competitive Region

Rodriguez, DA
Muñoz-Loustaunau, A
Pendleton, T
Sussman, JM
1998

The role of an architecture for deploying intelligent transportation systems in finding solutions to regional transportation problems is analyzed. The concept of a competitive region, a region with changing economic interests, stakeholders, and borders, is reviewed. The competitive region motivates finding solutions to transportation problems of regional scope. The concept of a regional system architecture is then introduced as a catalyst for reaching coordinated regional solutions. The regional architecture’s flexibility and ability to bring different stakeholders together make it...

Smart Corridor Evaluation Plan: Conceptual Design

Wachs, Martin
1994

This report presents the Conceptual Design Plan for evaluating the effectiveness of the Smart Corridor Demonstration Project. The specific objectives of this report are to: 1) develop a conceptual structure for the Smart Corridor evaluation, 2) define evaluation data requirements and collection procedures, and 3) select and/or develop data reduction and data analysis methodologies. Overall, the Smart Corridor is designed to obtain improved utilization of existing roadway facilities, both freeway and arterial, through the use of Advanced Traveler Information Systems ( ATIS) and Advanced...

Expanding the Urban Transportation Infrastructure Through Concession Agreements: Lessons from Latin America

Rodriguez, DA
1999

Driven by fiscal constraints and disappointment with the performance of state-provided services, national and subnational governments have turned to the private sector for solutions in financing, constructing, and providing transportation services. Key concession package features and their effect on reaching closure in urban transportation agreements are analyzed. Case studies drawn from the major attempts to develop urban transportation infrastructures in Latin America through concession agreements are considered. Results indicate that features common to large infrastructure...
