$226 b exports)

Aging Infrastructure – Underinvestment or

Disinvestment in Critical Links Could be Costly…

What did we do?

• Developed a DTA model of the El Paso/Juarez region

• Ports-of-entry• Traffic signals• Accurate geometry• Traffic flow models

Dynamic Traffic Assignment Modeling Framework to Simulate

Traffic Effects of Failures…

Americas (BOTA)

Preliminary Results and Conclusions

For the term immediate to disruption, the loss is at an accelerated rate of $2.5 million per day for the shippers and carriers. Peak periods have the highest loss.

Longer term costs on a per day basis are lower but will accumulate depending on length of replacement schedules and ability of trucks to shift to alternate POEs besides Zaragoza or Santa Teresa.

Regional spillover costs (indirect and induced) are not considered.

Possibilities include exploring mitigation strategies and looking at important supply chains and trade flows.

15

Concluding Remarks (contd.)

Vital for agencies to consider regional resilience as part of preparedness and,

Continuity planning for businesses along corridors.
