Segment traffic counts are conducted along a roadway during a typical week for a consecutive seven-to-14-day period for Interstate IAJR projects with microsimulation and one to two days for other projects. This is based on coordination with the TxDOT project manager and collected in 15-minute increments. Segment traffic counts are often separated by direction to analyze directional split. For analyses that use microsimulation as part of an IAJR, segment traffic counts are recommended to be conducted for a period of at least 7-to-14 consecutive days.
