Welcome to DC!
The District of Challenges
R&A Engineering2
Sixth most congested city in the U.S.
Drivers spend an average of 63 hours
stuck in congestion each year
Population of the city doubles daily
with commuters from VA and MD
Making the challenge multi-jurisdictional
Two-thirds of trips made by automobile

Welcome to DC!
The District of Challenges
R&A Engineering3
DDOT is currently using a variety of
TSMO and ITS solutions to address
congestion from daily commuter traffic
or recurring congestion
Seeking new solutions to begin
addressing sources of non-recurring
congestion

non-recurring congestion
Existing DDOT permitting
system collects generic closure
schedules
DDOT desires higher-
resolution information about
active road closures

Conclusions
R&A Engineering29
Two unique solutions to address
non-recurring congestion in the District
First: A real-time road closure reporting application that collects
specific information about active road closures
Second: A novel strategy that repurposes existing traffic data for
improvements to TSMO policies during and after special events

Conclusions
R&A Engineering30
The presented solutions:
Use technology that is ready for deployment
Promote a high benefit-to-cost ratio
Build from DDOTs existing partnerships
Leverage DDOTs existing data sources
Do not require changes to existing driver behaviors
