New Technologies and Strategies to Cut Down Emissions

Wednesday, November 11th, 2015
Figure 2. Share of Ride-Sharable Trips Relative to Total Trips by Scenario

MINETA TRANSPORTATION INSTITUTE Executive Summary It is widely recognized that new vehicle and fuel technology is necessary, but not sufficient, to meet deep greenhouse gas (GHG) reductions goals for both the U.S. and the state of California. Demand management strategies (such as land use, transit, and auto pricing) are also needed to reduce passenger vehicle […]

The Benefits of Transit in the United States

Thursday, August 20th, 2015
Figure 2. Average Benefit-Cost Ratios by Urbanized Area Population Using Only Congestion Savings Benefits

This white paper documents the findings from a review of available research literature on the benefits and costs of transit systems in the United States. The primary goals of this research were to 1) identify benefit-cost (b-c) ratio estimates for U.S. transit systems, and 2) identify the main categories of monetized benefits that derive from transit services in the U.S.

What Do Americans Think About Public Transit?

Thursday, August 6th, 2015

The analysis of the poll questions found that strong majorities of people believed that transit brings a number of specific benefits to their community, especially congestion relief and accessibility to vulnerable residents. Strong majorities also support improvements to transit as a general concept. However, fewer people support the general concept of increased spending on transit, and considerably fewer than half support raising any specific tax to increase transit funding, except for sales taxes, which usually enjoy majority support.

Results of a Six-Year Transportation Funding Survey

Figure 1. Supporta Levels for the Tax Options Surveyed in 2015

This report contributes to the understanding of current public sentiment about increasing transportation taxes by presenting the results from the sixth year of an annual telephone survey investigating public opinion about a variety of transportation tax options at the federal level. The specific taxes tested were ten variations on raising the federal gas tax rate or creating a new mileage tax, as well as one option for creating a new federal sales tax.

Passenger Flows in Underground Railway Stations and Platforms

Wednesday, June 24th, 2015
Figure 1. Conceptual Diagram of Rail Station Passenger Flow

Why people choose to travel by private car rather than by public transit is of major concern to transportation planners and transit operators. For some reluctant would-be riders, the answer might be summed up by the words of Yogi Berra when asked why he no longer patronized a popular St. Louis nightspot: “Nobody goes there anymore. It’s too crowded.”

The Great East Japan Earthquake: Lessons for California High-Speed Rail

Friday, May 29th, 2015
Figure 1. Comparison of the Moment Magnitude and Corresponding Energy Release of Large Earthquakes and Other High-energy Phenomena

Earthquakes are a reality in both Japan and California. Seismically active areas lie near and under high-speed rail systems in Japan and along the proposed route for the California High-Speed Rail Authority’s (CHSRA) developing system. Japanese high-speed lines have withstood significant earthquakes without a single loss of life. Their experiences are instructive for California as it develops its system.

Streetcar Transit in the Modern U.S. City: A Multiple-Case-Study Investigation

Thursday, March 5th, 2015
Figure 1: A Streetcar in Portland, Oregon

This study examines the transportation performance of modern-era streetcars operated in five U.S. cities: Little Rock, Memphis, Portland, Seattle, and Tampa. The objective of the study is to examine streetcar performance, test hypotheses about variation in performance through a combination of empirical analysis and insights derived from key informant interviews, and to identify lessons for other cities that operate or are contemplating operating streetcars

Effects of Gas Prices on Transit Ridership

Monday, December 8th, 2014
Figure 3. Boston: Retail Gasoline Price and Unlinked Passenger Trips for Bus

Between 1999 and 2011 consumers in the U.S. experienced an unprecedented increase in and fluctuation of gasoline prices. In July 2008, gasoline prices exceeded $4 per gallon, marking the highest price in real value in U.S. history. In the same year, the nation’s transit ridership reached 10.7 billion trips, the highest level since the Federal- Aid Highway Act of 1956…The rising gasoline prices were considered to have resulted in substantial changes in travel behavior in terms of trip taking, choices of travel destinations, selection of vehicles for higher fuel efficiency, or travel mode. A change in travel mode from driving to transit results in a higher level of transit demand and ridership for transit agencies. With this background, gasoline price increases in the last decade have generated substantial interest in developing a better understanding of how people respond to fluctuations in gasoline prices—particularly with respect to switching modes from driving to public transit—so that transit agencies can better prepare for higher demand for their services during periods of increased gasoline prices.

Modeling Taxi Demand with GPS Data

Wednesday, July 23rd, 2014
Figure 1. Taxi Pickups and Drop-Offs from 5:00 p.m. – 6:00 p.m.

Taxis provide an alternative to conventional public transit services in many cities, and understanding the demand for taxis requires consideration of the role that taxis serve in the greater transportation system. This report presents the results of a study to model taxi demand across time and space, explicitly accounting for the presence and quality of transit service. The primary objective of the study was to identify the factors that drive taxi demand and to understand how this varies by location and time of day. This was accomplished by developing demand models for taxi trip generation and mode choice that explicitly account for the characteristics of transit service in the neighborhoods where trips are made. The resulting insights are useful for making regulatory, planning, and engineering decisions about how to manage taxi markets, accounting for their role in the transportation system.
