Project Overview The InterCounty Connector (ICC) / MD 200
18 mile tolled highway linking I-370/I-270 with I-95/US 1 I-370 to MD 97: Opened Feb 23, 2011 MD 97 to I-95: Opened Nov 22, 2011 I-95 to US 1: Scheduled to open Spring 2014
ICC Construction Six-lane $2.5 billion facility
I-95 to US 1: 4 lanes Joint Effort
Maryland SHA Managed construction
MDTA Financing (50%) Own, Operate & Maintain
SHA – State Highway Administration
MDTA – Maryland Transportation Authority

Toll Collection Tolls
Collected via E-ZPass transponder or video tolling Video tolling rates are 50% higher than posted E-ZPass
rates Vary by day and by time of day to promote free-flow
Trip Construction Unique to ICC
Trips are constructed by considering entry and exit points combined with allowable trip times between each of the gantries.
Back office system can fill in missing “middle trips” Missing one end only reduces the toll but allows for definitive
collection vs. the entry/exit which cannot be calculated Video tolls posted within 3-7 days of transaction/trip

Incident Management Created the MD 200/ICC IMTF
MDTA/MSP/SHA/MoCo/MNCPPC Conducted a joint on-site exercise
Evaluate response to HAZMAT incident
Recommendations Communications
Add talk groups to achieve interoperability Have approved MOUs on crash scene investigation in place
IMTF – Incident Management Task Force
MSP- Maryland State Police
MoCo- Montgomery County
MNCPPC – Maryland-National Capital Parks and Planning Commission

Lessons Learned
Coordination Improve communication between Agency, IT, Design
Builder and Toll Integrator (TI) Conflicting scopes of work and schedules increased the scope
of installation services beyond what was stated in the contract Established Activation Team
Network Design should be approved and locked down prior to installation
Project Implementation Phased over a number of years
Not all functionality came online at the same time, creating the need for additional verification efforts

Lessons Learned Business Rules and Reports Business rules should be well defined
Different requirements from “cash” reports It is essential to perform complete end-to-end
testing Complete end-to-end testing is essential to demonstrate
that the reports function properly before going live Revenue Day vs. Calendar Day Involve Finance and Audit before design

Lessons Learned
Coping with a Dark Highway Blooming from vehicle headlights
Little to no ambient light present at gantry sites
Design change for future lanes Place DVMS cameras pointing downstream
Retro solution not fully identified Infrared cameras Filters

Lessons Learned
Trip Construction Need to fully understand complexities before
implementation Business rules/reports should be well defined Involve all stakeholders at early stages of design Need additional time to construct trips, OCR
