COMMERCIAL VEHICLE SURVEY - TECHNICAL SUMMARY

Published August 2012

The commercial vehicle survey for the Corpus Christi Urban Transportation Study (CCUTS) area was conducted during the period between September and December 2010. ETC Institute was contracted by TxDOT to conduct the commercial vehicle surveys for the study area, with technical assistance from the Texas A&M Transportation Institute (TTI). Prior to these surveys, a pilot study of 25 commercial vehicles that were owned, leased, or operated by recruited workplaces was carried out. The over-sample rate was established and a target number of 419 businesses was established for the CCUTS survey area.

The commercial vehicle survey collected data on cargo transport vehicles and fleet or service vehicles of area governments and businesses.

HOUSEHOLD TRAVEL SURVEY - TECHNICAL SUMMARY

Published December 2013

This survey represents a sample of household demographic and travel characteristics for a Monday through Friday weekday during the school year from the spring of 2009 to the spring of 2010. For participating households, each member of the household was provided a diary to record his or her travel. The survey data were retrieved from participants by phone at a prearranged call-back time within two days after their specified travel date. Every attempt was made to interview all persons within each of the 1,888 randomly selected households that participated in the survey. In many cases, a proxy provided information for household members who were not available. Adult members of the household usually reported the activities and trips for minors in the household. A small number of households chose to return their completed diaries by mail, in lieu of providing their trip information over the phone.
