  2. Contents • Background • Study Area • Data • Methodology • Preliminary Results • Conclusion and Future Work 2

  3. Background • Freight movements expected to increase 42 percent by the year of 2040 • NFSP (US DOT, 2016) reported that assuming no capacity changes, truck and passenger vehicle traffic will increase peak-period congestion by 34 percent in 2040. 3

  4. Adverse Weather Events • With significant increases in freight volumes, the impacts from severe weather events to port truck traffic may cause an economic loss in Texas and throughout the region • Because of the ports’ coastal location and global climate change, adverse weather events, which include flash floods and hurricanes, have become more frequent and severe. 4 https://ane4bf-datap1.s3-eu-west-1.amazonaws.com/wmocms/s3fs-public/ckeditor/files/t2m_anomaly_month_1_to_month_10_2017.png?.meW3juo.WlZXdyG2iiYHmf2PgJcLMC0

  5. Hurricane Harvey, 2017 • A Category 4 storm, Hurricane Harvey, brought catastrophic floods to the Houston area inflicting $125 billion in damage • In the first week, the storm directly affected nearly 10 percent of all US trucking and other transportation throughout the Texas coastal area due to flooded roadways and damaged infrastructure. 5 Source : Forbes, CNN, Wikipedia

  6. Texas Freight Mobility Plan • Maintaining infrastructure and improving system efficiency by increasing the resiliency of the State’s freight transportation system and effectively responding to natural and man-made disasters • A short-term regional plan: developing strategies to minimize the impacts on multimodal freight network caused by frequent adverse weather events • A long-range plan: designing flexible and reliable freight transportation as a regional priority 6

  7. Project Goals • Characterize the port truck movements by identifying operational patterns by associated industry and service types and evaluate system response during adverse weather events • Investigate the port truck flows from the port of Houston throughout its metropolitan region (Houston-Galveston Area Council) and further destinations in the region 7

  8. Study Area 8

  9. The Port of Houston, TX • Located in the fourth-largest city in the US • The busiest port in the U.S. in terms of foreign tonnage, • Second-busiest in the U.S. in terms of overall tonnage, and • Sixteenth-busiest in the world Growth in Houston Export Containerized Tonnage 9 http://www.h-gac.com/freight-planning/ports-area-mobility-study/documents/180124.HGAC.Project.Workshop-Rev-180124.pdf

  15. Streetlight GPS Data • Large-sized GPS data will be used to represent individual trip characteristics such as travel time, origin-destination (OD), major route choice, and industry type • The larger coverage of GPS data provides a larger portion of vehicle traffic and reduces sampling bias in traffic estimates. • Before and after Harvey to understand the effect of weather events on truck behaviors faced with a disrupted network 15

  27. Conclusion • Hurricane impacted OD movements and Link/Route choices during a peak and/or recovery times depending on the… – type of ports – types of movements (regional vs. local) • These spatially and temporally varying patterns (or resiliency) require further investigations on more disaggregated level of impact analysis

  28. Future Work • Develop resiliency measures to understand and quantify the impacts from Harvey • Develop performance measures to detect the deviation/abnormality from typical behaviors • Understand how a single (or multiple) link disruption(s) may affect local or regional movements

  29. Potential Applications • Understanding distinct port truck activities and the behavioral changes of freight movements during severe weather events such as Hurricane Harvey represents the first step for fast system recovery to minimize economic, social, and human impacts from the events • Agencies may adopt a variety of mitigation strategies to enhance resiliency and sustainability of port truck operations by accurately predicting their route choices, transport mode choices, and delivery schedule changes caused by severe weather events. 29
