Quantifying Transportation Relationships

April 8, 2020
Posted in What's Happening

April 8, 2020

CMU Mobility21 UTC researcher and CEE’s Sean Qian studied the relationship between Uber and public transportation, demonstrating variance between time of day and location.

His work was described in the following article published in CMU’s Civil & Environmental Engineering News Spring 2020 newsletter…

In our modern world, it’s easy to get across town. With companies such as Uber and Lyft, known as transportation network companies (TNC), passengers have plenty of options on how they will travel. Both TNCs and public transportation leaders rely on data to influence their policies, so Associate Professor Sean Qian set out to study the relationship between TNCs and public transportation in Pittsburgh. In a recently published paper in the journal Transportation, Qian’s Mobility Data Analytics Center focused on whether consumers were substituting public transit with TNCs, making last-minute decisions to choose a TNC over public transportation based on fares.

TNCs and public transportation can have a complementary relationship—that is, the TNC can help fill service gaps in public transportation. It is impossible for buses, subways, and light rail to easily connect every single street, but TNCs can cover the first and last portion of the trip. Between public transportation and short TNC rides, consumer costs can be kept to a minimum, while maximizing accessibility to the community.

However, according to CMU PhD student Rick Grahn, it can be difficult to understand the relationship between TNCs and public transportation; sometimes there may be no relationship at all.

“Some of the current literature says bus riders are quite different from people who would use Uber, so maybe there’s not a lot of interaction
between the two,” Grahn says. “It’s hard to make any definitive conclusion
of what drives travelers’ choice and how those choices may vary from
time to time, and from location to location.”

Researchers can look at the bus ridership before and after TNCs begin servicing an area, but changes may not be directly related to the TNC, making it almost impossible to tell why bus ridership changed. The best way to learn about the relationship between TNCs and public transportation is to analyze trip-level data, but such data can be difficult for researchers to access.

To acquire trip-level-like information, Qian and his team used Port Authority data that counts how many people board passing buses and tracked Uber prices at 10 different hand-picked locations around Pittsburgh.

There are many variables that decide if a person takes the bus or a TNC,
so Qian accounted for the weather, nearby events, traffic, and other
bus stops. To smooth out daily inconsistencies, data was taken over a
six-month period.

Qian was most interested in learning what an increase, or surge, in TNC
prices does to bus ridership. Surge pricing works by comparing how many
drivers are in an area with how many people need rides.

Because an increase in TNC riders results in an increase in price, it
might seem natural that bus ridership would increase during these surges.
However, that doesn’t always seem to be the case.

At stops on a university campus, which were filled with students, this
assumption held. Qian states that this is probably related to students’ low
budgets and the fact that Carnegie Mellon and University of Pittsburgh
students have unlimited public transportation use incorporated into
their tuition.

However, at locations that connected local buses and downtown along
a dedicated busway, there was a decrease in bus boarding, suggesting
a substitutional relationship between TNC and public transportation.
This might also indicate that TNCs are providing last-mile services to
passengers using the dedicated busway. Otherwise, no correlation was
found between price surges and bus boarding.

While these results may be unique to Pittsburgh, researchers can apply
the same model to other cities to find relationships there. According
to Grahn, once the relationship is understood, targeted policies can be applied at a neighborhood level, ensuring a complementary and efficient relationship between transportation options.

“Congestion fees can be applied to TNC trips in specific congested areas during commute times to promote more space efficient modes of travel,”
Qian and his co-authors conclude. “Data-informed policies that consider
emerging modes of travel are central to limiting rising congestion costs
and improving mobility for vulnerable populations.”

At the locations where significant changes in bus ridership occurred,
the trend was restricted to specific times of the day and either weekdays
or weekends. This fact alone is important, according to Qian. Large macroscopic research may not yield the significant, small-scale trends his
team found.

“The main thing this research is showing is that it is important to
look throughout the day and at all these neighborhoods with different
characteristics,” Grahn says.

Students from PA Rural Robotics Initiative Visit CMU

July 3, 2019
Posted in What's Happening

June 27, 2019

Today, 15 students from the Franklin Area High School went to Carnegie Mellon University for the day. The students, all part of the PA Rural Robotics Initiative, traveled almost 2 hours each way to get a glimpse into some of CMU’s programs and resources.

Organized and supported by CMU’s Mobility21 University Transportation Center and the Robotics Institute, the visit included:

  • A discussion of transportation & technology
  • An introduction to making traffic “smarter”
  • A tour of the NavLab where the students saw and learned about autonomous vehicles
  • A tour of the Field Robotics Center where the students learned more about aerial robotics
  • A networking lunch where the students met and talked with members of the 2019 CMU Robotics Institute Summer Scholars cohort

When asked what she thought of the experience, Grace said “I really enjoyed learning about the autonomous vehicles and our discussions with the summer scholars. Thank you, CMU!”

Tim Heffernan, the Executive Director of the PA Rural Robotics Initiative said “Although geographically Carnegie Mellon isn’t too far from home, sometimes these types of opportunities and institutions seem worlds away to these students. Having the chance to meet the summer scholars and interact with the world’s best in their professions will change how these kids view themselves and their futures. We couldn’t be more excited about, and grateful for, the opportunity that our friends at CMU have provided for these young people. Events like today have a positive impact on our kids and our region.”

In addition to the students and Mr. Heffernan, five chaperones accompanied the group:

  • Mrs. Jill Foys, Northwest Commission, Director
  • Mr. Trenton Moulin, Bridge Builders Community Foundation, Executive Director
  • Mr. William Vonada, Cranberry Area School District, Superintendent
  • Dr. Jody Strausser, Clarion University of Pennsylvania, Associate Professor Computer Information Science, PA Rural Robotics 2019 Volunteer of the Year
  • Mr. Albert Abramovic, Venango County Commissioner. He said he was impressed with the day’s program and was grateful for the opportunity to join the students for the day.

One of the Mobility21 UTC’s focus areas is Education & Workforce Development.  Research and technology is only one half of the new mobility equations. The transportation industry is being deluged with disruptive technologies just as its current, aging workforce faces mass retirement. Educating, training and inspiring the currently and next generation of transportation professionals is critical to the success of new technology. Helping coordinate and participate in the visit from the PA Rural Robotics Initiative is one way the Mobility21 UTC is engaging the next generation of transportation professionals.

In 2018, Franklin Area High School had four lonely VEX robots that students traveled around Pennsylvania and West Virginia with, searching for teams to compete against. Fast-forward to the end of this June and those four robots have 180 new companions right next door. Together they make up the Pennsylvania Rural Robotics Initiative, a consortium of 11 school districts, one technology center, and an intermediate unit that all share a common robotics platform and curriculum. Twenty-five schools, covering five counties, have found like-minded friends in higher education, business and industry, state and local government, non-profits, and regional economic and workforce development that not only support their initiative but help it to thrive.

The Traffic21 and Mobility21 Institute’s leadership team have been trusted advisor since the conception of PA Rural Robotics and continues to look for ways to support their mission. Both faculty and graduate students from the Robotics Institute are working to bring CMU and these young STEM students together. PA Rural Robotics was also excited to find themselves partnered with a team of CMU undergraduate students as part of the 2019 Information Systems Spring Project. The Office of Outreach and Engagement have provided a menu of options that can further the CMU connections as the initiative grows. The most recent Carnegie Mellon connection was with the CMU CS Academy. PA Rural Robotics plans to introduce their member schools to the CS1 course and discuss the potential it could have in expanding computer science offerings within all of the member districts.

Smart Mobility Challenge Project: Traffic Impact Study of CSX Pittsburgh Intermodal Rail Terminal and Mitigation Plans for McKees Rocks

May 6, 2019
Posted in What's Happening

May 6, 2019

In September 2017, CSX Transportation began operations at its newest Pittsburgh Intermodal Rail Terminal, located in Stowe and McKees Rocks. The facility provides shippers a new transportation option to move freight to and from the region and enhances the area and the company’s competitive advantage through greater connectivity. However, studies show the development of the facility will also add to a number of trucks in and through the Borough of McKees Rocks, increasing demands on the existing infrastructure and increasing congestion to already congesting roadways.

Located along the south bank of the Ohio River just a few miles from downtown Pittsburgh, McKees Rocks & Stowe Township is home to 13,000 residents.

To study this traffic increase and possible mitigation strategies, the Borough of McKees Rocks applied for this new development and its traffic impacts to be a research project as part of Traffic21’s Smart Mobility Challenge. As a winning project, the CDC of McKees Rocks were partnered with CMU’s Mobility Data Analytics Center (MAC) to conduct an in-depth analysis of the potential growing traffic impact in high temporal and spatial resolutions.

During the research, Mobility Data Analytics Center (MAC) develops a large-scale regional traffic model that simulates nearly 700 thousand of trips of cars and trucks during a typical weekday. Using a variety of data sets, MAC was able to simulate individual trucks and cars and model route choices, travel time and mixed traffic flow conditions. The result includes the travel time, travel delay, vehicle-mile-traveled, fuel use and emissions for each road segment and intersection by time of day. In addition, the team examined the effectiveness of traffic management strategies in different scenarios.

During a recent project update meeting with community representatives shared that being chosen as a Smart Mobility Challenge project provided them a predictive model (that would normally be out of reach for communities like McKees Rocks) to help analyze truck traffics impacts in their community.

Although this research project focused on several particular applications such as trucks and roadway usage to demonstrate the method and leverage resources, the methodology can be applicable and scalable to other cities and regions, and to any general disruptive change to the infrastructure network. The research completed in McKees Rocks could also be of value to various groups interested in infrastructure, travel demand management, green design, environmental policies and more.

Now that the research part of the project is complete, the next steps for McKees Rocks includes a review of the research, engagement on discussions about the project results, and the provision of input for the decision makers to consider.
