Integrative Public Transport in a Segmented City: Reflections from Jerusalem

Jerusalem is perhaps an extreme case of residential and travel market segmentation. It is comprised of four different 'cities', which partially overlap in space: The Jewish-Zionist city; the Palestinian city; the Jewish ultra-orthodox city and the global-tourist city. While the specific delineation of these cities is unique, Jerusalem can be seen as representative...

Friday Transportation Seminar at Portland State University - June 1, 2018

Friday Transportation Seminars at Portland State University have been a tradition since 2000. With over 450 seminars presented and recorded (access the archive of seminars here), we host both visiting and local scholars to share the latest in research, technology, and implementation in transportation.

OVERVIEW

Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. 

This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership and the costs of fare collection systems. How much does it save to reduce cash acceptance, verses ridership and equity impacts?

We will also present a cost-effectiveness framework that combines a qualitative and quantitative analysis and use this model to explore case scenarios in our three cities. The model shows that adding a retail network to...

Summaries:

Evaluating Driver and Pedestrian Behaviors at Enhanced Multilane Midblock Pedestrian Crossings: Case Study in Portland, Oregon This study examines driver and pedestrian behaviors at two enhanced midblock pedestrian crossings in Portland, Oregon. One crossing is on a five-lane arterial with a posted speed of 35/45 miles-per-hour (MPH) and features six rectangular rapid flash beacon (RRFB) assemblies and a narrow median refuge. The other crossing is on a suburban arterial with four travel lanes and a two-way left-turn lane. The crossing is enhanced with four RRFB assemblies and a median island with a “Z” crossing, or Danish offset, designed to encourage pedestrians to face oncoming traffic before completing the second stage of their crossing. Approximately 62 hours of video have been collected at the two locations. A total of 351 pedestrian crossings are analyzed for driver compliance (yielding) rates, pedestrian...

Abstract: How do commuter rail riders choose access modes? This presentation discusses the results of an analysis of access mode choice by riders of one of the first U.S. suburb-to-suburb commuter railroads, the Westside Express Service (WES) in the Portland, Oregon metropolitan area. The study uses on-board survey data collected by the region’s transit agency, Tri-Met, during WES’s first year of operation. The data include observed access mode choices, historical mode usage, and subjective assessment of WES attributes. A hierarchical choice model was estimated, using attributes of the access trip and station areas as well as rider characteristics. The estimation results showed evidence of pre-WES mode inertia effects in choosing drive access, pro-sustainability attitudes in choosing bike access, the importance of comfort for light rail and auto access modes, as well as strong positive station-area effects of connecting bus lines and parking space provision. The hierarchical choice model revealed significant substitution effects between drive and light rail modes and between bike and walk modes. This study provides potentially valuable insights to agencies for the purposes of station-area planning and targeted marketing efforts.

Can Location Value Capture Pay for Transit?

Successful public transit systems increase the value of locations they serve. Capturing this location value to help fund transit is often sensible, but challenging.

This presentation will define location value capture, and synthesize lessons learned from six European and North American transit agencies that have experience with location value capture funding.

The opportunities for and barriers to implementing location value capture fall into three categories:

Summary: Where and when does overcrowding happen on TriMet's bus network? Which routes have the best on-time performance? Portland State University and TriMet have collaborated to make this kind of data available to anybody through Portal, PSU's transportation data archive for the Portland/Vancouver region. This presentation will cover the use of General Transit Feed Specification (GTFS) data for mapping TriMet’s performance data and the development of Portal’s innovative transit application. In the MAP-21 era of performance management, see how tools like Portal can support enhanced agency decision-making as well as community engagement.

Abstract: Our speaker for May 14, 2010 is Gill V. Hicks, Director Southern California Operations for Cambridge Systematics, Inc.  For more than ten years, Mr. Hicks served as the General Manager of the Alameda Corridor Transportation Authority (ACTA).  The $2.4 billion Alameda Corridor consolidated harbor-related railroad traffic onto a single 20-mile corridor between the ports of Los Angeles and Long Beach and the railroad mainlines near downtown Los Angeles.  Mr. Hicks’ responsibilities included overall management of the agency, building consensus, estimating benefits and costs of the project, generating political support, testifying before U.S. Congress, State Legislature, regulatory bodies, city councils, funding agencies and other stakeholders; developing a financial plan, raising funds, coordinating with railroad, trucking, and shipping businesses, and managing contracts for the project.

Mr. Hicks will discuss the major challenges faced by the project, including negotiations with three competing railroads, several municipal governments, utilities, regulatory agencies, contractors, and funding entities.  The process for consensus building will be discussed. Major lessons learned will be described, including methods for reducing project risk, keeping on schedule and within budget. Mr. Hicks will also touch on the challenges facing the agency as...
