Project Overview
Gridlock Avoidance System
(G.A.S.)
ODU CS 410/411
presented by David Grant PM
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

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.)

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

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

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
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
