Federal Highway AdministrationUS Transportation CollectionObservations and initial examination of ADT and peak-hour volume data on Denver regional arterials suggests questions asto if and why they are happening, and what the implications are on corridor travel and accident patterns? This proposedresearch task will investigate these trends and address questions, to assist CDOT in better determining which improvementswould more likely decrease accident experience while improving corridor capacity. The research will focus on a selectedfreeway section and corresponding regional arterials corridors. The study will address the effects of arterial traffic volumediversion patterns and the discontinuities on freeway versus arterial safety parameters.The final product of this research will be a report presenting the traffic and safety statistics and trends along a selectedfreeway/arterial corridor, with conclusions as to what improvements are most likely to improve safety and corridor thru-puton both
