And we're working on additional infrastructure: the subway tunnel that connects the project, the arena, with existing subways.
"Light rail" is an appealing form of mass transit for cities today, since it requires relatively little infrastructure — no subway tunnels or elevated tracks — and it brings in federal subsidies.
Over many months, there was talk of using of motion detectors, infrared sensors and sophisticated software to protect a wide range of infrastructure, from subway tunnels and bus depots to bridges and tunnels.
In the deals, corporations bought infrastructure like subways and bridges from municipal authorities and then leased them back to the authorities.
As always, the machine added to urban infrastructure: the subways with their fixed five-cent fare, new bridges, and an expanded park system brought the boroughs together and added to its authority.
For instance, urban planners can use massive GPS location data from taxis to help analyzing traffic anomalies [6], area functions [7], travel routes [8], etc. Nowadays, modern urban has a variety of public infrastructures including subway stations, overpasses, office facilities, sports arenas, supermarkets, convention centers, hospitals, and entertainment parks, to name a few.
Every walking surface is below or above infrastructure, train sheds, subways, underground passageways.
Subway infrastructure improvements involved track replacement, signal modernization and station reconstruction.
"I was away working for so long," said Arthur Bethell, a white-haired supervisor in the subway infrastructure department.
The government built new infrastructure, including a subway line that goes directly to the park's front gate.
