Abstract: Urban arterials often represent complex venues of transportation operations, co-mingling non-motorized users with transit services and a wide variety of land uses and traffic patterns. This presentation presents results related to the evaluation of a new Adaptive Traffic Control System (SCATS) on Powell Boulevard in southeast Portland. The presentation will discuss challenges and opportunities associated with the evaluation of new technologies and the development of comprehensive urban arterial performance measures.

Abstract: A new way of measuring Level of Service for bicycles, pedestrians, and transit is planned for the next Highway Capacity Manual. Are these the right tools to help us plan and build the system we want? If not, what answers do these tools give us and how should we use them? This presentation will review the approaches to multi-modal Level of Service at the national and local levels and discuss efforts to validate the HCM methods. It will also cover the effect of our LOS policies on climate change and explore ways that we might tweak our analysis to get a more accurate picture of the transportation system for all users.

Abstract: Portland is planning to launch a bike share system. Bike share is a new form of public transit that is rapidly spreading through the United States. In 2009, bike share operated in two U.S. cities. Today, 20 US cities operate systems with another 15 in the planning stages. In several cities, including Denver, Minneapolis and Washington, DC bike share has demonstrated the ability to bring new people to bicycling while reducing single occupancy vehicle trips. How will bike share work in the nation’s most bike friendly city (doesn’t everybody already have a bike)? What challenges does Portland face, and what opportunities does bike share offer to reach the Portland’s Bike Plan for 2030’s ambitious goals?

Speaker Bio: Steve Hoyt-McBeth is a project manager in the Portland Bureau of Transportation’s Active Transportation Division. He has worked on bike share at PBOT since 2008. Steve also manages PBOT’s employer and commuter Transportation Demand Management program, SmartTrips Business. He has 15 years experience working with local governments and neighborhoods in Oregon and California on land use, energy and transportation issues. Steve is a graduate of the University of Oregon.

Abstract: We study the impact on productivity of a specific operating practice currently adopted by some demand responsive transit (DRT) providers. We investigate the effect of using a zoning vs. a no-zoning strategy on performance measures such as total trip miles, deadhead miles and fleet size. It is difficult to establish closed form expressions to assess the impact on the performance measures of a specific zoning practice for a real transportation network. Thus, we conduct this study through a simulation model of the operations of DRT providers on a network based on data for DRT service in Los Angeles County.

For fifteen years, scholars have claimed that accessibility-based transportation planning is at the brink of becoming a new paradigm. In contrast with traditional mobility-based planning methods, which focus on the cost of transportation per mile, accessibility-based planning methods place more importance on people's ability to reach various destinations and their access to transit systems. Its use may trail behind traditional planning methods nationally, due to vague definitions, momentum of traditional performance measures, and other factors. However, this webinar argues that accessibility-based planning is demonstrably necessary in shrinking cities across the U.S., and especially among minority populations in those cities.

As shrinking cities’ need for accessibility-based planning is distinct, the challenges to accomplishing it are also distinct and rather severe. Again, this is especially true when planning for minority populations, for whom there is often a level of mistrust in the policy process itself which must be overcome. After presenting evidence of both the especial need for and the challenges inherent in accessibility-based planning in shrinking cities (and especially among minority populations), this presentation proposes potential strategies for implementation and for applying this method in those scenarios in which it is most needed.

Social Transportation Analytic Toolbox (STAT) for Transit Networks

 

PRESENTATION ARCHIVE

Miss the webinar or want a look back?

OVERVIEW

This webinar will present an open-source socio-transportation analytic toolbox (STAT) for public transit system planning. This webinar will consist of a demonstration of the STAT toolbox, for the primary purpose of getting feedback from transit agencies on the tool's usefulness. We are especially interested in hearing about any improvements that would aid transit agencies in implementing it.

The STAT toolbox was created in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies, to aid in evaluating and enhancing the performance of public transit systems. The toolbox enables the integration, analysis, and visualization of two major new open transportation data sources—social media and GTFS data—to support transit decision making. In this webinar, we will introduce how we...

Topic: Examining the Role of Internal Planning Decisions in Improving Transit Performance and Economic Outcomes
Summary: Scholars and practitioners continuously seek best practices to increase transit ridership, efficiency, and modal share. The ongoing suburbanization and decentralization of U.S. metropolitan regions brings new challenges for accomplishing these goals. Investigating possible strategies for improving transit outcomes in the existing socioeconomic setting, scholars from the Florida State University have pointed to the role of internal performance factors. In a series of research studies, they have found that improving transit service characteristics, such as frequency, connectivity, regional coverage, intermodal integration, as well as decentralization of network structures, could result in increased transit ridership and productivity. These positive effects could be observed even in auto-oriented, low-density environments. 

This presentation will briefly summarize the previous findings regarding the role of internal factors in improving transit performance and elaborate on the most recent study, which has attempted to assess the economic effects of implementing planning strategies based on adjusting the internal...

Abstract: The historic divide between spacial planning and transport planning has caused many crucial insights to remain stuck on one side of the divide. When dealing with public transit, Jarrett Walker argues that planners urgently need a clearer view of transit's fundamentals. These are often lost track of amid the excitement of a particular project, resulting in development where efficient (and therefore abundant) transit is impossible. This talk reviews the much-ignored principles of efficient transit networks, bus or rail, and argues that true "transit-oriented development" must be consist with those principles. These principles yield surprising conclusions both about many New Urbanist projects, and also about the potential of 82nd Avenue and similar "sprawl arterials."

Speaker Bio: Jarrett Walker is an international consultant in public transit network design and policy.  He has been a full-time consultant since 1991 and has led numerous major planning projects in North America, Australia, and New Zealand.  He currently serves as a Principal Consultant with MRCagney based in Australia.  He provides expert advice to clients worldwide
