Synopsis: This is a short, accessible article that provides a synopsis of findings from the research titled “Tool Development to Evaluate the Performance of Intermodal Connectivity (EPIC)” in collaboration with UCLA Institute of Transportation Studies. This research has examined various factors that can substantially influence transit users’ perception of service quality at bus stops and trains stations, and also what factors transit managers think important to improve customers' satisfaction. Recently, the project has developed a tool for transit agencies to identify service quality improvements at transit facilities, which has been presented in the American Planning Association (APA) National Planning Conference in Los Angeles, April, 2012. Publications related to this research are listed under " FURTHER READING" on page 15.

 

Tool for Assessing Station Characteristics (TASC): Identifying Service Quality Improvements at Transit Stops and Stations

Authors: Allison Yoh, Norman Wong, Michael J. Smart, and Hiroyuki Iseki (2012)
Report
Synopsis: This particular poster presentation describes a web-based analysis tool that is hosted by the UCLA Institute of Transportation Studies and is publicly available to transit agencies interested in identifying which service quality changes (e.g. amenities, information, lighting, etc.) to transit stops/stations are most important for improving levels of transit users’ satisfaction.  This program is based on a series of research projects funded by California Department of Transportation since 2005 (see www.its.ucla.edu/research/EPIC/) in collaboration with researchers from multiple universities, including Hiroyuki Iseki from the National Center for Smart Growth.  This phase of research—TASC project—is groundbreaking in that it provides planners an analysis of the relative importance of various improvements, uses community-based input, and can be applied at the level of individual stops/stations, across a group of stops/stations, or across the transit system as a whole.  The program provides a graphical representation of users’ levels of satisfaction juxtaposed on top of the importance of various service qualities.  In short, it provides a clear indication of how best to invest increasingly scarce transit resources to improve customer satisfaction in attributes that matter to transit customers.  The poster focuses on a description of the process for using the tool – downloading the survey forms, conducting a user survey, uploading survey results, and downloading analysis results – and highlights examples of how the analysis can be performed at different levels of analysis to meet different needs.

 

Hate to Wait: Effects of Wait Time on Public Transit Travelers’ Perceptions

Report
Synopsis: A large and growing body of research suggests that transit users hate to wait. Given broad policy goals to increase public transit use in U.S. cities, this research sheds light on cost-effective ways to increase transit use by decreasing the perceived burdens of waiting at stops and stations. The goal of this study was to determine (a) the relative importance of stop and station amenities and attributes and (b) how the importance of these amenities and attributes varies with wait time. For this goal to be accomplished and for the duration of wait time when amenities become important to be determined a transit user survey that asked more than 2,000 travelers to rate both the importance of amenities at their stops or stations and their wait times was analyzed. Regardless of wait time, safety and on-time performance were paramount to riders; these also ranked highest relative to all other station and stop amenities examined. Lighting, cleanliness, information, shelter, and the presence of guards were less important to travelers when waits were short, but were more important with longer wait times. Thus, improving service frequency and reliability reduces the need for amenities at stations. This end suggests that when transit managers have a choice and when riders feel safe and secure managers should favor service improvements over station and stop amenities. Finally, some amenities become more important with long wait times, such as restrooms and food and drink facilities. Although provision of basic needs amenities is intuitive, restrooms and food and drink sales are most likely present at high-passenger-volume, high-service-frequency stops and stations, where they are valued least by travelers.
