Title: TRAFFIC DATA COLLECTION USING A COMPUTERIZED DATA ACQUISITION SYSTEM
Accession Number: 00642382
Record Type: Component
Availability: Find a library where document is available Abstract: Traffic characteristics such as headway, flow rate, speed, acceleration, wheelbase, and lane position have traditionally been collected using manual procedures, which are labor- and time-intensive and generally allow only one characteristic at a time to be collected. However, a computerized data acquisition system (CDAS) using tape switch sensors on the roadway will allow many traffic characteristics to be collected simultaneously. CDAS has three major advantages over a manual collection system: it requires fewer total person hours to collect the data, it offers improved measurement precision and accuracy, and it collects data continuously. An overview of a CDAS is presented, the methods used to extract the desired traffic characteristics from CDAS data are discussed, and insights and experiences obtained using a CDAS are offered.
