Project Overview Design a Geographic Information System (GIS) network and apply
TRANSIMS model.
Investigate strategies that will relieve IH 45 congestion and get residents out of harm’s way during an emergency evacuation.
Calculate traffic movements.
Enrich the dialog of decision makers as to their options to manage evacuation traffic.

PROJECT RELEVANCE • The Gulf Coast and
portions of the eastern people. U.S. are highly prone to hurricanes which require evacuation of thousands of people.
• DHS’ goal to improve disaster response is a focus of this research.

Project Relevance (cont.)
• Traffic volumes and routing from the simulation will advance knowledge for coastal communities that are susceptible to hurricane or other weather events.
• Better information available to decision makers can facilitate moving civilians from environmental hazards.

Method of Approach
Year 4 Year 5
• Develop temporal and spatial dynamic evacuation demand for Houston base evacuation conditions.
• Validate Houston base model and adapt evacuation model for Houston-Galveston per the backdrop of Hurricane Rita in 2005.
• Prepare for conversion of Houston data to GIS-format (per previously collected New Orleans data) and be included in ESRI Geodatabase .
• Solicit advisement from workshop attendees (specifically HGAC, TxDOT and Harris and Galveston Counties) about evacuation of vulnerable populations to potentially include bus based component to simulation.

Progress to DateProgress Towards Year 4 MILESTONE
Progress Toward Year 5 MILESTONE
Two evacuation scenarios have been successfully run.
• One emphasizes greater use of arterials as a complement to freeways for evacuation. • The second assesses an incentive for evacuees to leave early by reducing one freeway options for later evacuees.
Develop network layer for transit service from Galveston zones. GIS network completed
with all activity zone locations based on Galveston Transit system is complete.

Proposed Activity Based on advisement of stakeholders, a
bus based evacuation plan for vulnerable populations will be assessed using simulation software.

Current Translations
Hosted a symposium at Houston Galveston Area Council regarding the results of this research. Attendees: HGAC Harris and Galveston County OEM Texas Department of Transportation

Symposium Feedback• Simulation of small area within the region
has merit.• OEM would not deliberately close IH45,
but extreme value in case of emergency closure.
• Greater use of arterials is an option to improve distribution of traffic.

Product & Looking Forward
Product: Multi-modal, regional evacuation travel model and simulation tool for large-scale disasters.
Looking Forward:
• Year 5 will create a new network for Zone A (Galveston vicinity) that will be designed to assess transit as another evacuation option.
•Year 6 will examine utilization of the HOVs for evacuation from Zone A.
