Using National Freight Information to Study the Interactions Between Heavy Trucks and Passenger Cars Under Traffic Incidents or Emergencies

摘要

This case study demonstrated that national level freight movement data can be adapted to local traffic studies on trucks. Although the national freight movement information can not be applied directly in small geographic regions, it remains to be an important data sources for the metropolitan planning organization. With supplemental data from local agencies, a truck O-D table can be built to reflect local-level truck traffic volumes. Such a local truck O-D table can greatly improve transportation analysts' ability to study the increasingly congested urban highway traffic.
