Multimodal Freight Analysis & Capacity Modeling Objectives
• Freight Analysis – Network level freight traffic forecasting under various policy scenario including freight diversion across modes
• Capacity Modeling – Forecasting mode specific capacity under existing and improved infrastructure profile due to forecasted freight demand.
• Other Tools – Plug in other policy tools (HERS-ST, ITIC, State PMS etc.) for freight diversions and forecasting of economic analysis based capital funding requirement.

Developed to Address Transportation Policy Questions and Project Prioritization
• How effective is it (the system)?
• Implications of an ineffective system?
• Where are the needs?
• What can we fix (potential improvements)?
• What’s the best fix (benefit to cost ratio)?
• How much (the funding)?
• Which project has the highest priority?

The Modes
• Highway
• Rail
• Water
BUSINESS SENSITIVE
Freight Demand and Capacity Analysis -Interface
• Four Components
– Infrastructure Profiles
– Performance Measures Calculator (capacity, delay, etc.)
– Generalized cost base network demand assignment model
– Plug-inn interaction with user (FHWA, State, MPO) defined demand model
BUSINESS SENSITIVE
Infrastructure Profile
• Ideal for Corridor Analysis
• Visualization of corridor performance index under various “what if” analysis scenario
BUSINESS SENSITIVE
Corridor Infrastructure Profiles
BUSINESS SENSITIVE
Capacity and Performance Calculator
• Highway
– HCM2000
– Modular design – can be plug in any external module
• Rail
– Ideal and Practical Capacity
– Policy level accuracy with default parametric co-efficient
– Subdivision and Corridor Specific
• Water
– Army core of engineers
