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

Contractual aspects

CS 250

Collect and format data for input

CS 300u

Survey of real-life traffic patterns

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)
