Test deployment of new on-demand hub & shuttle mobility system at U Michigan; connected & automated vehicles & big data

A test of a new hub-and-shuttle urban mobility system will take place on the University of Michigan’s North Campus. Its creators say the proposed system could deliver riders to their destinations in as little as half the time of the existing bus system at a lower cost, eventually using a fleet of autonomous shared vehicles. The limited test deployment would likely mark the world’s first on-the-ground implementation of such a system.

Called Reinventing Public Urban Transportation and Mobility (), the proposed system combines aspects of Uber-style ridesharing, fixed-route buses and light rail into the hub-and-shuttle system. It would combine high-frequency buses serving the busiest transportation hubs with a fleet of about 50 on-demand shared shuttles to get riders to and from those hubs.

RITMO carries basic research in data science, from descriptive to predictive and prescriptive analytics, spanning research in data mining, machine learning, optimization, computational economics, marketing, and urban planning.

Passengers would hail rides using a smartphone app that would calculate the most efficient journey for a given destination—it could be a direct shuttle ride from A to B, a shuttle followed by a bus trip or any similar combination. The app would track the progress of each passenger and each vehicle, feeding data to a back-end system that would be optimized in real time to minimize congestion and maximize efficiency.

The on-demand vehicles would have human drivers at first, but the designers hope they would eventually be replaced with autonomous vehicles, lowering costs further, says RITMO lead research Pascal Van Hentenryck, the Seth Bonder Collegiate Professor of Industrial and Operations Engineering at U-M.

Development of the system is funded with a $1.4 million grant from the Michigan Institute for Data Science. If the test deployment is successful, the team plans to expand the system across U-M’s campus within a year, to all of Ann Arbor within three years and eventually to the Detroit area as well.

It’s similar in some ways to the ride sharing that’s available now, but much more sophisticated. Obviously you can’t have everyone using something like Uber because that would cause massive congestion. But on-demand hub-and-shuttle can provide some of the convenience of point-to-point travel along with the efficiency of a high-frequency transit system.

The proposed system was inspired by a 2015 study that examined the viability of a similar approach in Canberra, Australia. Led by Van Hentenryck, that project showed that a hub-and-shuttle system would likely cost the same or less than a traditional bus system because fewer fixed-route buses would be required.

A bus costs many times more than a car, so high-capacity buses often aren’t the most efficient way to serve areas where demand is low. Serving those areas with small, on-demand vehicles would be much more efficient and more convenient for riders.

—Pascal Van Hentenryck

Van Hentenryck says that if the new system is successful, it could gradually replace U-M’s existing fixed-route bus system. The core U-M system would remain free to users, although he believes that riders eventually will be able to choose from several different transportation options for a given journey—some free, some not.

The key to making it all work, Van Hentenryck says, is data. The team has already begun collecting that data, asking students and staff to volunteer anonymous GPS tracking information through the existing U-M smartphone app. The detailed data will enable them to apply data mining, machine learning and mathematical optimization techniques to tease out patterns and make predictions about how people move around U-M’s campus. They’re also using existing data from the U-M and Ann Arbor public transportation systems, as well as demographic and mobility data.

From a data science standpoint, it’s a fascinating optimization problem. What are the mobility patterns in Ann Arbor? How do you define the size of the fleets, where do you put the high-frequency buses and how many? Those are the kinds of questions we’re answering with the data we collect in this initial part of the study.

—Pascal Van Hentenryck

The team, which also includes the U-M School of Information and Information Technology Services, hopes to have an initial version up and running by early 2017.

Other U-M departments involved in the project include the U-M Transportation Research Institute, Department of Emergency Medicine, Taubman College of Architecture and Urban Planning, Department of Electrical Engineering and Computer Science, U-M Parking and Transportation Services, and Advanced Research Computing Technology Services. The 2015 study upon which the project is based is titled “Benders decomposition for the design of a hub and shuttle public transit system.”

Would be beneficial if the over paid drivers are replaced with automated drive units?

Stop these studies paid by the taxpayers and invest your own money if you want to sell products and services, stop this communism project from the democrats and republicans that do not want to support trump and said to vote for Clinton. These currupted state projects are all endorsed by HarvyD.

Vote for trump and help eradicate worldwide communism from the internet. We are surrounded by stupid car and energy projects here in GCC and autobloggreen and what we need is a higher gasoline mpg car. Build my gasoline air hybrid car that i ordered here last week.

The article fails to explain how "Big Data" in the Title is applyed. (Attention all Hadoop SW engineers. Please send us your resumes. You will be employed to stand around looking like you are working on something important.)

Throw the reader more buzz-words and they can be fooled, P.T. Barnum style.
