Friday, March 25th, 2016Streetfilms: Five Fabulous Questions for Streetfight’s Janette Sadik-Khan
Wednesday, March 23rd, 2016
Just as former New York City Transportation Commissioner Janette Sadik-Khan launched her multi-city book tour for “Streetfight” (along with co-author Seth Solomonow) we were able to grab her for a few minutes in the pedestrian paradise of Washington Square Park to ask her what we thought were five eclectic questions.

Tuesday, March 8th, 2016
Laura Erikson, Community Development Coordinator in Lewis and Clark County, MT discusses how EPA is making a visible difference in Helena, MT. EPA Brownfields funds were used by the County to investigate contamination at a site that was regarded as the most blighted property in town. After completing the environmental assessment, the Montana Business Assistance Connection, with help from the City and EPA, was able to purchase the site and restore it to residential use standards. Today it is ready for redevelopment. Ms. Erikson explains what the newly cleaned site will mean for the community, calling it a “catalyst” that will benefit the whole area.

Tuesday, March 8th, 2016![Fig. 1. Fastest and simplest paths in primal and dual networks. (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)
AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE
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.
Students Design the City of the Future
Friday, March 4th, 2016
Future City is a cross-curricular program that lets students in the 6th, 7th, and 8th grades do the things engineers do: identify problems, brainstorm ideas, design solutions, test and retest, build and then share the results. Future City is a program of DiscoverE.

Thursday, March 3rd, 2016
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.

Dear Friends,
It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.
Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.
We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.
We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
