Summary | To improve the efficiency and sophistication of methods for collecting, processing, and analyzing constantly observed data such as traffic volumes and travel speeds, the following were carried out: (1) development of method for estimating traffic volumes in sections with no vehicle detectors and development of a method for processing traffic analysis travel time data for Regional Development Bureaus; (2) case analysis of traffic characteristics of trunk roads using constant observation data; and, (3) annual renewal of traffic survey unit data that serve as fundamental data for collecting and analyzing constant observation data. |
