As federal and state policies place increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making, there is a gap in such measures of transportation and land use systems. This seminar reports the results from a research project aiming to fill the gap in the type of applications and policy areas covered by existing measures. Modeled after the popular Consumer Price Index, the project refines and develops a transportation cost index (TCI) measure for transportation and land use systems by tracking the time and monetary costs of transportation for households as they travel to satisfy their daily needs. The TCI can be used in applications ranging from monitoring historical and projected trends (benchmarking), to evaluating and comparing scenarios outcomes (scenario evaluation), and it is capable of representing policy areas not sufficiently covered by existing similar measures.

The seminar will review similar performance measures,...

Transportation costs are typically a household’s second largest expense after housing. Low income households are especially burdened by transportation costs, with low income households spending up to two times as much of their income on transportation than higher income households (Litman, 2013).

Thus, access to location efficient housing is especially important to low income households, including those who use a housing voucher to help pay for housing costs.

This seminar presents the results of a two-year project supported by the Portland region's four public housing authorities to design and test tools to help people with housing vouchers find location efficient housing. We examine the challenges that residents faced and discuss policy implications.

Topic: Managing User Delay with a Focus on Pedestrian Operations

Across the U.S, walking trips are increasing. However, pedestrians still face significantly higher delays than motor vehicles at signalized intersections due to traditional signal timing practices of prioritizing vehicular movements. This study explores pedestrian delay reduction methods via development of a pedestrian priority algorithm that selects an operational plan favorable to pedestrian service, provided a user defined volume threshold has been met for the major street. This algorithm, along with several operational scenarios, were analyzed with VISSIM using Software-In-The-Loop (SITL) simulation to determine the impact these strategies have on user delays. One of the operational scenarios examined was that of actuating a portion of the coordinated phase, or actuated-coordinated operation. Following a discussion on platoon dispersion and the application of it in...

A ‘travel plan’ is a travel demand management strategy that contains a package of site-specific measures designed to manage car use and encourage the use of more sustainable transport modes. Much of the existing literature on travel plans focuses on their application in workplaces and schools. Travel plans can be required for new residential developments as part of the land use planning and approvals process. However, there is limited understanding of the extent to which they have influenced travel behaviour. This presentation focuses on the assessment of travel plans developed for new residential apartment developments in Melbourne, Australia. Consideration is given to both the quality of travel plans for new residential developments and their effectiveness in terms of their impact on travel behaviour.

Professor Geoff Rose is the director of the Institute of Transport Studies at Monash University in Melbourne, Australia. Geoff's research and teaching activities cover sustainable transport,...

A NITC research project from Portland State University introduces a method of cleaning up land use data, for use in improved transportation models.

Transportation and land use are closely interdependent. Considerable work is underway, in Oregon and elsewhere, to develop models that integrate the two.

Planners creating these models often spend the bulk of their time preparing data on the various land uses. Many times the data, gathered from diverse sources, is incomplete and requires the planner to find missing information to fill in the gaps.

In fields outside of transportation, there have been considerable advances in techniques to do this. Data-mining and machine-learning techniques have been developed, for example, to systematically detect fraud in credit data, reconcile medical records and clean up information on the web.

In the transportation modeling community, by contrast, most efforts to tackle the problem are tied to a specific model system and a chosen study area. Few have produced reusable tools for processing land use data.

Liming Wang, lead investigator of the project Continuous Data Integration for Land Use and Transportation Planning and Modeling, offers such reusable...

Streetcar_people_alphabet National Geographic recently described Portland as the City that “…gets almost everything right; it’s friendly, sustainable, accessible, and maybe a model for America’s future” (Cover story, Dec. 2009). Portland has a shared vision of a livable city, articulated in many different ways. It is seen in neighborhood self-help projects, big municipal investments, enlightened developers that build infill projects consistent with city plans, and the highest recycling participation rate in the country.  Taken together Portland is a city that is environmentally responsible, and conscious of both street level and of global impact of doing things right.

 


Early History

Arguably, Portland’s first act of ‘building green’ was in 1892, when it built a reservoir network to protect and preserve the sole source of its drinking water, the pristine . Today, this 102-square mile conservation zone provides ample fresh water to a region of half million people

Fast forward almost 100 years and the same ethic motivated Portlanders to reject a Robert Moses-style highway plan...
