Gross Domestic Product Increasing
Population growth increasing

Construction Cost increasing
The cost of right of way increasing
Funding constraints increasing
Need to continue the economic viability of the
corridor increasing

Changing the

PROBE DATA PROVIDED BY UNIVERSITY OF MARYLAND
CHARTS CREATED BY SCDOT
Other Interstate Routes
• Not enough funding to build out of congestion
• Development impacts limits capacity improvements
• Economic development not following the 20 year
design life of projects
• Some Capital improvements providing only 2-5 years of
relief
• Silver bullet solutions are becoming challenging
• Best hope of maintaining a status quo on congestion
• Travel Demand Management and Modal Options are
going to become the new normal with higher
expectations
• Data is available to support and direct investment on a
system wide level (Corridors, Access Management etc.)
• Partnerships and stakeholder buy-in becoming
essential

Public Engagement
• Three tiered approach to public engagement
• Alignment with on-going studies and projects
in study area
• Goals
– Alignment in data collection, technical analysis
– Alignment in messaging
– Alignment in regional goals and performance
measures
• In-Person meetings with all three tiers (OnGoing)
• Project Workshop (Spring 2016)
• Data collection (On-Going)
– On-line surveys
– Web based project information
– Data sharing across projects and agencies
– Interviews with steering committee, stakeholders
Traffic Forecasting and Analysis
• SCDOT Statewide Travel Demand Model
(TransCAD)
• Simulation Model under development
(TransModeler)
• Base Year of 2015
– Weekday A.M. and P.M. peak hour periods
– Model was developed using traffic data collected
in 2015
• Forecast Year of 2040
Performance measures will be developed to
compare alternatives in all four buckets
• Regional Performance
– Model will be used to test future scenarios
– Mode shift and travel demand strategies will be
evaluated system wide
– Model will be used to evaluate freight movements
and obtain truck performance measures
• Corridor and Interchange Level Performance
– Reduction in travel demand evaluated for operations
– Mainline and Interchange design modifications
• Travel Demand and Simulations Models
• Technical Memoranda
• Existing Conditions Report (Spring 2016)

o Identify Priority Transit Service
o Develop a technical memo with service area map with associated
data and identify location priority regional transit corridors
• Deliverables:
 Stakeholder outreach and coordination
 An overview map
 Evaluation matrix
 Identify feasible and practical stop and service pattern
locations by corridor
 Show potential access of proposed transit services and
proposed station locations
 Aerials of preferred park and ride lot locations
 Cash flow analysis
 Final Report
