Riding First Class: Impacts of Silicon Valley Shuttles on Commute & Residential Location Choice

Dai, Danielle
Weinzimmer, David
2014

Employer-provided private shuttles have become a prominent part of the transportation network between San Francisco and Silicon Valley. As the Bay Area plans for transportation investments to meet sustainability goals and accommodate future population and employment growth, an understanding of the role of regional commuter shuttles becomes increasingly important. This study investigates the impacts of private shuttles on commute mode and residential location choice by conducting a travel time comparison and surveying shuttle riders. The authors find that the provision of shuttles and...

Examination of Key Transportation Funding Programs in California and Their Context assesses the congruence between funding programs and state goals for transportation. Particular attention is given to major funding sources, such the State Operation and Protection Program, and programs designed to promote key state goals, including the Affordable Housing and Sustainable Communities program, the Transit and Intercity Rail Capital Program, the Transformative Climate Communities program, and the Sustainable Transportation Planning Grant program.

The Ethical Challenges and Professional Responses of Travel Demand Forecasters

Brinkman, Anthony P.
2003

Thirty years ago scholars first presented convincing evidence that local officials use biased travel demand forecasts to justify decisions based on unstated considerations. Since then, a number of researchers have demonstrated convincingly that such forecasts are systematically optimistic-often wildly so-for reasons that cannot be explained solely by the inherent difficulty of predicting the future. Why do modelers-professional engineers and planners who use quantitative techniques to predict future demand for travel and estimate its potential impact on built and proposed transportation...

In the fall of 1966 a short course on ’’Urban Mass Transit Planning” was developed by the Polytechnic Institute of Brooklyn with the assistance of the New York State Science and Technology Foundation and the cooperation of the U.S. Bureau of Public Roads. The course was presented both by the Polytechnic Institute in Brooklyn and by the Institute of Transportation and Traffic Engineering, University of California, and University of California Extension, in Asilomar, Calif.A set of course notes was written for that offering and reproduced in limited quantity. Presented herein is an expansion...

Pooling Passengers and Services

Forscher, Teddy
Shaheen, Susan, PhD
2018

In the past ten years, passenger and goods movement transportation systems have evolved rapidly. Shared mobility providers are filling gaps in service and creating new markets for delivery; vehicle fleets continue to electrify; and pooled services are increasing vehicle occupancy. The uptake of innovative pooled services, as well as automation, promise to continue the trend of transformative change. As the private sector continues to advance, there is a great need for institutional flexibility in managing and coordinating all users of transportation infrastructure, particularly on the...

Estimating Bicycle and Pedestrian Demand in San Diego

Jones, Michael
Buckland, Lauren
2008

This paper introduces the concepts behind estimating bicycle and pedestrian demand and provides an example of the development of a sketch-plan method for estimating bicycle and pedestrian demand from land use in San Diego County. The paper describes the methodology involved in collecting counts for the currently ongoing Seamless Travel project. The Seamless Travel project intends to develop a model for estimating bicycle and pedestrian demand within San Diego County. The project methodology includes conducting bicycle and pedestrian counts and intercept surveys over a two-year period...

Pedestrian Volume Modeling for Traffic Safety and Exposure Analysis: The Case of Boston, Massachusetts

Raford, Noah
Ragland, David
2006

This paper examines three types of pedestrian volume models in light of their usefulness for estimating pedestrian exposure for pedestrian safety research. The need for pedestrian flow data as part of pedestrian exposure and safety analysis is outlined, and the background of each type of model is discussed. It then selects the space syntax network analysis model to estimate pedestrian volumes for the city of Boston, Massachusetts. It was found that the model was able to accurately predict pedestrian flows (r-squared 0.81, p-value < 0.0001) after incorporating distance to transit...

San Francisco PedSafe II Project Outcomes and Lessons Learned

2009

This paper presents the project outcomes and lessons learned from the San Francisco PedSafe, a comprehensive pedestrian safety planning and engineering project funded by the Federal Highway Administration. It assesses the effectiveness of the Phase I pedestrian safety plan targeted to higher-injury areas by evaluating the Phase II implementation of a range of mostly low-to-moderate-cost innovative safety improvements.A total of 13 countermeasures (comprised of nine general engineering countermeasures and four Intelligent Transportation Systems (ITS) countermeasures) were implemented by the...

Community Pedestrian Safety Engagement Workshops in California

Babka, Rhianna JoIris
Cooper, Jill F
Alfsen, Wendy
Sabin, Marilyn
2011

The Community Pedestrian Safety Engagement Workshops are a community capacity building program to involve local residents in community pedestrian safety. The focus of these workshops is to engage, educate and empower residents to ensure they have the skills, knowledge and resources they need to become active in improving pedestrian safety in their neighborhood, district, city or county. This program uses pedestrian planning and community engagement curriculums as a framework for the content, and goes beyond this to tailor each workshop to the individual community needs, ensuring genuine...

Roadway and Infrastructure Design and Its Relation to Pedestrian and Bicycle Safety: Basic Principles, Applications, and Benefits

Ragland, David R

2013

Road deaths are forecast to double by 2020, with the burden falling most heavily on low- and middle-income countries and, within those countries, on the most vulnerable and poorest road users. Half of the 1.2 million people killed and 50 million injured in road crashes each year are pedestrians, motorcyclists, bicyclists, and users of unsafe public transport; and more than 90 percent are from low- and middle-income countries. Because these are the areas where rapid motorization is taking place, the issue of safety in increasingly multi-modal environments is now of critical importance,...
