This study, which focused on the Silicon Beach Innovation District in Los Angeles County, CA; the Historic Technology District in northwest Austin, TX; and Research Triangle Park, one of the oldest research parks in the United States, located between Durham, Chapel Hill, and Raleigh, NC, finds that public transportation could be the determining factor in the success of innovation districts in the United States.

(A) In the primal network of the New York City (NYC) metropolitan system, a simplest path (light blue) from 125th Street on line 5 (dark green) to 121st Street on line J (brown) differs significantly from a fastest path (gray). There is only one connection for the above simplest path (Brooklyn Bridge–City Hall/Chambers Street) in Lower Manhattan. In contrast, the above fastest path needs three connections (5→F→E→J). We compute the duration of this path using travel times from the Metropolitan Transportation Authority (MTA) Data Feeds (see Materials and Methods). We neglect walking and waiting times. (B) In the dual space, nodes represent routes [where ACE, BDFM, and NQR are service names (49)], and edges represent connections. A “simplest path” in the primal space is defined as a shortest path with the minimal number of edges in the dual space (light-blue arrow). It has a length of C = 1 and occurs along the direct connection between line 5 (dark-green node) and line J (brown node). The above fastest path in the primal space has a length of C = 3 (gray arrows) in the dual space, as one has to change lines three times. [We extracted the schematic of the NYC metropolitan system from a map that is publicly available on Wikimedia Commons (45).]](https://www.infrastructureusa.org/wp-content/uploads/2016/03/transitsystems.jpg)

Cities and their transportation systems become increasingly complex and multimodal as they grow, and it is natural to wonder whether it is possible to quantitatively characterize our difficulty navigating in them and whether such navigation exceeds our cognitive limits. A transition between different search strategies for navigating in metropolitan maps has been observed for large, complex metropolitan networks. This evidence suggests the existence of a limit associated with cognitive overload and caused by a large amount of information that needs to be processed. In this light, we analyzed the world’s 15 largest metropolitan networks and estimated the information limit for determining a trip in a transportation system to be on the order of 8 bits.
CTfastrak is the region’s first dedicated mass transit system in more than 50 years. Carrying more than 16,500 riders each weekday, the system centers around an exclusive 9.4-mile guideway dedicated to the BRT system that links central Connecticut communities. It reduces traffic congestion and shortens commute times for commuters in Hartford, West Hartford, Newington and New Britain, CT.

City centers across the nation are experiencing revival and renaissance. Urbanized communities are becoming increasingly desirable, with more people showing interest in living and working in locations with a variety of mobility, cultural, entertainment, employment, and housing options. A combination of transportation strategies is needed to accommodate these shifting attitudes and accompanying influx of residents, employees, and visitors to urbanized areas – even more so in downtown areas already experiencing high concentrations of residential and employment populations.
Michael P. Melaniphy is president and chief executive officer of the American Public Transportation Association (APTA) and president of the American Public Transportation Foundation. Melaniphy’s entire career has been in public transportation, with more than 30 years of both public and private sector leadership experience.
“As a kid growing up you had a binary choice: you were either a bus kid or you were a car kid. You were one of the two. And you look at today’s environment and it’s a multi-modal environment. We have evolved as a society to understand that now it’s about mobility choices…So as we look at what are the best utilizations of our scarce resources in a community, people are looking at the full assortment of choices, and as we look at the unbelievable growth that’s going to come in the population set of this nation we’ve found that paving our way to a solution is not the best choice.”

Seattle cartoonist Ellen Forney discusses the process of developing two murals, “Crossed Pinkies” and “Walking Fingers,” for Sound Transit’s art program, STart. The two iconic, hand-painted murals greet riders at entrances to the Capitol Hill Station, part of the University Link light rail extension opening March 2016.

Private providers are anxious to keep the discussion going with public transit agencies, emphasizing that the partnerships are a start toward reducing overall car ridership and encouraging more transit use—while providing them with a possible well of new customers…“There’s been a lot of mutual curiosity,” said Peter Gould, Uber’s senior transportation policy associate. “We’re excited about having these conversations and having these connections, and talking to each other about the other not in a negative sense, but about how we complement public transit and the impact of Uber.”
Planner and biking advocate Veronica Davis discusses her decision to give up her personal car, and the future of urban transportation options.
