Project: Analyzing the Impact of the I-85 Bridge Collapse on Regional Travel in Atlanta (Masoud Hamedi, Sepideh Eshragh, Mark Franz, Przemyslaw Sekula)
Lead Agency: CATT, in support of Georgia Department of Transportation
Supporting Agency: N/A
PDA Suite (& RITIS) Tools Used: Massive Data Downloader, Trend Map,
Description: On March 30, 2017 a bridge on I-85 north of Atlanta collapsed from an intense fire, closing all five lanes of highway in each direction for 45 days. At the June 8th RITIS User Group meeting, the CATT Lab presented how to use RITIS for: Traveler information; Real-time coordination, and; After Action Reviews. The University of Maryland's CATT used various PDA Suite tools for a follow-up "deep-dive" analysis of the roadway network's performance before, during and after the collapse.
Highlights: CATT researchers clearly depicted area impacts though travel time reliability visuals, and also used the data to develop a new "Comparative Congestion Index" to indicate the relative value of TTI during the road closure, compared to average TTI before and after the bridge collapse period.
