project goal
Project Goal
  • Our main goal is to develop a computer-based simulation model to mimic the behavior of the Hampton Roads Interstate System south of the Mercury Blvd. Interchange to the Battlefield Blvd. Interchange.
project sub goals
Project Sub-goals
  • We intend to provide city planners and transportation professionals with results that describe their system’s operations at current and modified vehicle flow rates in two formats: statistical and graphical.
  • This tool is necessary to support the interstate highway system in Hampton Roads which is a critical element to the infrastructure of society in the area.
project sub goals cont
Project Sub-goals (cont.)
  • Demonstration simulation of a small segment of the Hampton Roads interstate system for project validation and verification.
  • Market the project on a consultant basis (what ifs).
  • Completion by the end of the calendar year 2001
  • Y2K compliant software and hardware
competitive analysis
Competitive Analysis
  • Competitors
    • Other Traffic Simulation products
  • Strengths
    • Currently not being used by the local governments or VDOT
  • Weaknesses
    • Data must be in a usable format
    • Different localities maintain their data differently

evaluation methods
Evaluation Methods
  • During Fall Semester 1998 and Spring Semester 1999, there will be regular status and brainstorming session of the group and sub-groups.
  • During the implementation and Completion phase we will use accepted SEI standards (formal and one-on-one peer reviews, Test Readiness Reviews, Team Advisory Groups for customer acceptance).
potential problems
Potential Problems
  • Not possible to model current/historical traffic
  • Not possible to complete in time
  • Inadequate or unavailable data
  • Too expensive
  • No buyers
  • Already on market
  • Spending cutback
  • Experts:- Dr. Leathrum (ECE)- Dr. Overstreet (CS)- Mr. Dennis Watson (VDOT)
