5th Bi-Annual Border to Border Conference
Development of an Origin-Destination Matrix for the Paso Del Norte Region (Regional Master Network Phase IV)
McAllen, Texas November 19th , 2014
Background
The Center for International Intelligent Transportation Research (CIITR) is committed to enhancing the quality of life for the Paso Del Norte Region and to developing solutions that can be successfully applied in other U.S. border environments
Background
Project Phases:
1. Integration of the Transportation Network and Transportation Analysis Zones (TAZs) Ciudad Juarez and Las Cruces
2. Integration of El Paso’s Network and TAZs into the Regional Network
3. Exploring alternatives to build a regional Origin-Destination Matrix (ODM)
4. Developing the regional ODM (current)

Background (strategic grid for checking)
Background• Most common problems related to network-based
modeling at CIITR:• missing links• incorrect attributes• incorrect names• directionality and topology• lack of projection/coordinate system• no metadata
Literature Review
• Four-Step Trip based traditional Approach• Activity-based approach• Simplified Geographic Origin-Destination Generation
(SGODG)• Development of origin–destination matrices using mobile
phone call data• Dynamic Origin-Destination Demand Estimation and
Prediction for Off-line and On-line Dynamic Traffic Assignment Operation.
Summary of FindingsAlternative/Method
Approximated Cost (thousand
dollars)Advantages Disadvantages
Direct Measurements $420-$500Accurateness and reliability Cost and time consuming
Traffic Counts + Algorithms
$80-$90 Few steps for its implementation
Computer processing and algorithm development time
Simplified Geographic $40-$45Low-cost alternative Calibration and validation
Household Data (regressions)
$80-$110 Time and resources savings: quicker implementation than other methods
Household data acquisition (Ciudad Juarez)
TRANUS land use based $55-$65 Direct generation of a regional O-D
Calibration/Validation (International POE)
Cellphone Data $75-$82 Accurateness suitable for big areas
Relatively expensive, time consuming processing (Different cell providers policies)
Bluetooth Technology N/A Easy to implement, Excellent for External-to-External O-D
Not suitable for internal zones (O-D). Low capture range and high cost. No vehicle classification.
