"WMATA Metrorail Using ‘Big Data’ to Install Cellular Service" —— Passenger Transport

Passenger TransportDescription: 
“In the U.S., mobile LiDAR mapping technology had not been used in tunnels on any known project more than five miles in length,” Falken said. Metrorail engaged Maser Consulting, P.A., an engineering firm specializing in geospatial services, to test the mobile technology on a five-mile section.

The demonstration was successful. Next, the engineering firm made the “big data” readily available to Metrorail engineers and the cellular companies using uGRIDD infrastructure data management service, which allows users to view, measure, extract and download information in a secure server environment...

uGRIDD is on Passenger Transport: "CTA Use of LiDAR Improves Project Delivery And Capital Asset Management"

Passenger TransportDescription: “With the LiDAR data stored on uGRIDD anyone can zoom down a 360 degree LiDAR depiction of a rail line and find the data you need. It avoids time intensive and costly field work,” said Jim Harper, CTA chief engineer for infrastructure.Harper believes that asbuilt dimensions of the CTA rail infrastructure provided by LiDAR will help to create a good capital asset inventory of the system, improving capital asset management and application of CTA’s limited capital improvement funds. .... ...

     

 

Organized for Success: Geospatial Project Management on Chicago's Red Line

The Chicago Transit Authority's (CTA) Red Line is Chicago's busiest rail line with an average weekday ridership exceeding 250,000. It's a vital artery of the city, and runs 24 hours a day, 365 days a year—ideally, the Red Line should never shut down. So the CTA's recent rehabilitation of 10.5 miles of the Red Line was a major logistical challenge, especially since this particular stretch runs along the Dan Ryan Expressway and has a very narrow right-of-way.
