Every day transit riders ask the same question: when’s the next one coming? To answer this question, transit agencies are transitioning to providing real-time transit information through smartphones or displayed at transit stops.

Real-time transit information improves the reliability and efficiency of passenger travel, through:

  • shorter perceived and actual wait times,
  • an increased feeling of safety,
  • increased ridership, and
  • a lower learning...

Project OverviewTravel to Food: Transportation Barriers for the Food Insecure in Tampa Bay
Learn more about this research project by viewing the two-page Project Brief, related presentations, and the full Final Report.

In Tampa Bay, Florida, it's hard to get around without a car. For those who depend on transit, the simple task of bringing groceries home can take up an entire afternoon. 

Add the extra difficulty of food insecurity—which affects a wide variety of people and may mean they can't afford to go to the grocery store, but must travel to a food pantry—the task of procuring those groceries gets even more difficult. 

Now take away the possibility of transit. Where does that leave you? Hungry, wherever you are.

According to a new study from NITC investigators at the University of South Florida (USF), there are 136,401 people in Florida's Hillsborough, Pasco and Pinellas counties who are both food insecure and lack adequate access to transit.

Food insecurity affects a wide range of people and most acutely affects vulnerable populations such as children, pregnant women, seniors and individuals with disabilities.

The study, led by...

Transit-oriented development, or TOD, could be the “poster child” for sustainable urban development. It concentrates land uses, including commercial and multi-family housing, near transit stations so as to reduce car dependency and increase ridership. The benefits are manifold; increased community health, positive economic impacts, less harm to the environment and potentially greater social equity.

But what about affordability? In exchange for all these benefits, do TOD residents spend more money on transportation?

Normally we assume that travel is a means to an end, but the latest NITC report examines other benefits of travel—aspects that aren’t about reaching a destination.

One such benefit is travel-based multitasking. A good example of this is using time on a commuter train to listen to music, relax or get some work done. The simple enjoyment of a walk in the fresh air relates to another benefit, known as subjective well-being, in which the act of travel itself makes a person feel better. These intrinsic benefits can impact travel behavior and mode choice, but our current models don’t have any way to reflect this.

NITC fellow Patrick Singleton investigated the policy and planning implications of this in his dissertation, Exploring The Positive Utility Of Travel And Mode Choice.

"The way we analyze travel behavior assumes people want to get from A to B as quickly as possible. We don’t include the...

As social media comes to permeate every aspect of modern life, public transit is no exception.

Transit agencies are increasingly making social media an integral part of their day-to-day management, using it to connect with riders about system alerts, live transit arrival information, service disruptions and customer feedback.

However, there is very little evidence to show how effective these efforts really are in achieving agency goals.

Measuring the Impacts of Social Media on Advancing Public Transit, a NITC project led by Jenny Liu of Portland State University, seeks to provide a better understanding of how transit agencies use social media and to develop some performance measures to assess the impacts of social media on promoting public transit.

This project aims to measure how social media actually impacts agency goals like increasing recruitment and retention of transit riders; increasing resources and customer satisfaction; addressing system performance efficiency; and improving employee productivity and morale.

A survey of 27 public transportation providers across the country found that although 94% of those surveyed agencies used some form of social media, only 28% had a social media plan or strategy prior to implementation.

Liu’s research explores the types of performance measures that could...

A new NITC report offers a multimodal framework for transportation impact analysis – a welcome tool for professionals in many cities seeking more detailed data about non-drivers.

Improving Trip Generation Methods for Livable Communities, a research project headed by Kelly Clifton of Portland State University and Nico Larco of the University of Oregon, is the latest effort in an ongoing collaboration to create more open sourced, widely available data about non-motorized road users.

Over the last decades, cities have become more invested in fostering the conditions to support walking, biking and public transit.

The land development process presents a unique challenge.

Prior to a zoning change or new development, someone has to determine what its impact on the transportation system will be, and whether upgrades will be necessary to accommodate travelers to the new destination. Trip generation is the first step in the conventional transportation forecasting process.

Current trip generation methods used by engineers across the country tend to focus on motorized modes.

Without reliable trip generation rates for anyone but drivers, the transportation impact is difficult to predict. Certain land uses will draw far more walkers,...

The final report on this research is available now: Design for an Aging Population

Published in April 2017, this study sought to increase understanding of the obstacles faced by people with impairments in vision, hearing and/or mobility, which are common issues for older people, and generate physical product solutions.

The research shows that aging riders face conceptual, physical and social barriers that impact their willingness to use buses. Using the bus was seen as inconvenient, time consuming, physically draining and potentially frustrating. Priority seating areas designated for older and disabled users fill quickly. People with mobility challenges may use bulky walkers and require the availability of grab bars, and users of wheeled mobility devices need different device security. Several situations noted in the study show that physically challenged riders are subject to awkward, uncomfortable social dynamics more than other bus users. Innovation in easy access seats and secure WhMD stations at the front of the bus are critical for older users, as it makes riding the bus less draining and more safe.

This research was presented at TRB's 2017 annual meeting. See below for our coverage of the research at TRB.

NITC researchers have tested a method of collecting transportation behavior data using a smartphone app, with promising results.

The process could save transit agencies “hundreds of thousands of dollars,” says lead researcher Christopher Bone, and give them access to comprehensive, real-time data about their ridership, all without compromising passengers’ privacy.

Christopher Bone, Marc Schlossberg, Ken Kato, Jacob Bartruff and Seth Kenbeek of the University of Oregon designed a custom mobile application, which allows passengers to volunteer information about their travel habits, and recruited passengers to use it in a test case.

Their report, “Crowdsourcing the Collection of Transportation Behavior Data,” was released this month.

Download it here.

Participants were asked to use the app for three weeks on Lane Transit District’s EmX bus line located in the Eugene-Springfield area in western Oregon. Researchers placed sensors on the buses and at stops to detect when someone using the app was boarding. When a user came within range of a sensor, they...

Sunday, the first day of the Transportation Research Board annual meeting in Washington, D.C., is workshop day. Portland State University doctoral student Tara Goddard presents in a showcase of research stemming from the prestigious Dwight D. Eisenhower Transportation Fellowship program.

Goddard probed the question of why so many bicyclists die in traffic crashes. Cyclists are 12 times more likely to be killed in a crash than a driver or passenger in a car. She wondered what role drivers' attitudes toward cyclists might play.

Goddard's research uses a survey to measure drivers' attitudes and self-reported behaviors and to test drivers' implicit attitudes toward both other drivers and cyclists. She pairs the survey piece with a lab experiment that uses hazard-perception video clips to examine whether drivers notice cyclists. 

By this approach, Goddard hopes to understand drivers' attitudes and whether those attitudes can predict how they act on the road. That understanding can potentially lead to steps to improve cyclist safety. Her workshop runs 9 a.m. to noon in Room 202B of the Walter E. Washington Convention Center.
