Mobile Apps and Transportation: A Review of Smartphone Apps and a Study of User Response to Multimodal Traveler Information

In recent years, technological and social forces have pushed smartphone applications (apps) from the fringe to the mainstream. Understanding the role of transportation apps in urban mobility is important for policy development and transportation planners. This study evaluates the role and impact of multimodal aggregators from a variety of perspectives, including a literature review; a review of the most innovative, disruptive, and highest-rated transportation apps; interviews with experts in the industry, and a user survey of former multimodal aggregator RideScout users. Between February and April 2016, researchers conducted interviews with experts to gain a stronger understanding about challenges and benefits of data sharing between private companies and public agencies. Key findings from the expert interviews include the critical need to protect user privacy; the potential to use data sharing to address integrated corridor and congestion management as well as various pricing strategies during peak hours; along with the potential benefits for improving coordination between the public and private sectors. In March 2016, researchers surveyed 130 people who had downloaded the RideScout app to evaluate attitudes and perceptions toward mobile apps, travel behavior, and modal shift. The goal was to enhance understanding of how the multimodal apps were impacting the transportation behavior. The survey did found that respondents used multimodal apps in ways that yielded travel that was less energy intensive and more supportive of public transit. Looking to the future, smartphone applications and more specifically multimodal aggregators, may offer the potential for transportation planners and policymakers to enhance their understanding of multimodal travel behavior, share data, enhance collaboration, and identify opportunities for public-private partnerships....

Automated Speed Enforcement for California: A Review of Legal and Institutional Issues

Authors: Caroline J. Rodier, Ph.D, Susan A. Shaheen, Ph.D, Ellen Cavanagh Published: February 21, 2007 Abstract: Excessive speed is considered to be a major contributing factor to motor vehicle crashes and is thus an important focus of highway enforcement efforts. Automated speed enforcement programs have been widely applied outside the U.S. to address speeding-related safety problems. This literature review explores the potential benefits and barriers to implementing automated speed enforcement programs in the U.S. by examining the large body of literature on automated enforcement programs, including red-light and speed programs....

Travel of Diverse Populations: Literature Review

Authors: Evelyn Blumenberg, Moira Donahue, Susan Handy, Kristin Lovejoy, Caroline Rodier, Susan Shaheen, James Volker Published: September, 2007 Abstract: California is in the midst of a demographic transformation. According to the 2000 U.S. Census, nearly 30 percent of the California population is now foreign-born, more than 50 percent of the population belongs to a minority group, and the elderly (those 65 and older) comprise 11 percent of the population. Demographic forecasts suggest that these patterns will continue. California will continue to attract immigrants from throughout the world and will become increasingly diverse, racially and ethnically, with whites declining as a share of the population from 54 percent in 1995 to 30 to 34 percent in 2025, according to one forecast (Thomas and Deakin 2001). The percentage of seniors will also continue its upward trajectory in the coming decades, reaching over 13 percent by 2025 (Thomas and Deakin 2001). This demographic transformation raises an important question for transportation planners in the state: How can we ensure that the kinds of transportation systems and services we provide adequately meet the needs of our increasingly diverse population? To answer that question, planners need a better understanding of the travel behavior of diverse demographic groups within the state. As a part of a larger project studying the needs, constraints, attitudes, and preferences that influence travel choices and the outcomes of those travel choices among diverse groups in California, this report provides a review of existing literature on the travel behavior among specific demographic groups. In particular, this report provides a review of what is currently known about the travel patterns and transportation needs of the...

Innovative Corridors Initiative: Business Model Analysis

Authors: Rachel S. Finson, Virginia Lingham, Susan A. Shaheen, Ph.D Published: February 21, 2007 Abstract: The Innovative Corridors Initiative (ICI) Business Model Analysis examines public-private partnerships designed to deploy intelligent transportation systems (ITS) technologies that can improve transportation system management and provide real-time  information to users. This study builds on the business models proposed by industry in response to the ICI Call for Submissions (CFS). In addition, case studies examine the business models that are developing between the private and public sectors for roadside rest stop wireless Internet access, vehicle infrastructure integration, and Traffic.com, Inc. Caltrans’ current procedures for encroachment and procurement are reviewed briefly to identify possible areas of conflict that may need to be resolved prior to launching future CFS-style solicitations. Planning recommendations are provided to assist Caltrans with planning for future CFS-style solicitations, including considerations regarding goals, purpose and project partners, authority, and  post-demonstration relationships. Issues for Caltrans to consider pertaining to authority for CFS-style solicitations as well as the procurement of products that are demonstrated under these solicitations are highlighted....

Innovative Corridors Initiative: Call for Submission Process and Evaluation

Authors: Rachel S. Finson, Cynthia McCormick, Susan A. Shaheen, Ph.D. Published: March 14, 2007 Abstract: The Innovative Corridors Initiative represents an innovative business model for public agencies to partner with private industry to improve transportation system management and provide real time information to users. The Call for Submissions (CFS) issued by Caltrans, MTC, LA MTA, ITS America, and CCIToffered private industry access to public rights-of-way and data. However, no funds were offered as part of the CFS, meaning the companies that submitted a proposal and participated needed to have the capacity to self-fund their projects. This report provides a summary of the processes to implement the CFS, including public outreach, proposal review, negotiations between the public agencies and private companies, operations, coordination with the 2005 ITS World Congress in San Francisco, and project closure. Researchers chronicled the lessons learned throughout the process through a series of interviews conducted with the parties involved. Especially important were findings related to the public-private partnership for ITS deployment that the ICI project pioneered....
