Acquire micro-trajectories for driver behavior research

This is a specialized research application for 1-hertz TLAP (see description under TLAP Model Calibration), with special attention paid to measuring accurate second-by-second speed and lane changes, following distances, and gap acceptances for making turns across traffic or merging into new lanes. While imaging, a premium is placed on maximizing camera verticality, using higher-resolution lens-camera combinations across smaller coverage areas, and applying vehicle position tags with precision. This allows micro-movements of vehicles to be calculated, for greater understanding of driver behaviors while negotiating, say, freeway weaving or ramp merging sections, unusual signalized intersections, alternative-design facilities such as diverging diamond interchanges or modern roundabouts, transit buses that stop repeatedly on city arterials, highway links with narrow lane configurations, or while traveling along heavily-used two-lane highways.
