  1. I-95 Statewide Corridor Model in North Carolina: Unique Features and Challenges Presented to TRB Applications Conference May 9, 2013 Presented by Taruna Tayal, VanasseHangen Brustlin, Inc. Bill Thomas, Michael Baker Engineering

  2. Purpose of the Model and Unique Features • Toll feasibility for I-95 Corridor in the state of North Carolina • Understand travel patterns on I-95 in NC • Length of the corridor modeled – 182 miles • First study of this magnitude in US • Based on trip distance, studied 3 trip patterns for 2-trip purposes: • Separate diversion calculation application for long-distance and in-corridor trips

  3. 1 Data Collection 2 10 3 • ALPR data collected at 10 locations • Eight on I-95 • One each on: • I-40 , and • US-64 • ALPR data collected and matched for two vehicle class • Passenger Cars • Trucks • 48-hour tube class counts collected at each location • Travel Time data for I-95 and US-301 corridor 9 4 5 6 7 8 #

  4. Data Prep and Initial Skimming Toll Model Toll Diversion Highway Assignment Convergence Check & Feedback Not converged

  5. VoT and Model Formulation • Truck driver VOT does not change as a function of distance. • Non-CV VOT increases as distance increases. • Intercity travel VOT is higher than local travel VOT for passenger travelers • Different VOT for : • E-E : PC and Trucks • E –I intercity: PC and Trucks • E –I local: PC • I –I intercity: PC and Trucks • I –I local: PC Toll Share = (1 / (1 + eU)) U= a*(Timetoll – Timefree) + b*Cost + CToll + CETC + CCalib
