HomeMy WebLinkAbout100226 email - Press Release_ South Discovery_Jacob Miller Intersection ImprovedGood morning,
Jefferson County Public Works has recently upgraded the intersection of South Discovery Road and South Jacob Miller Road from a 2-way stop-controlled intersection to a 4-way stop-controlled
intersection.
For many years, this intersection had raised concerns from drivers due to its highly skewed alignment and vertical profile that led to odd driver behavior on Jacob Miller Road, including
mis-alignment of their vehicles with the intersection to better see oncoming South Discovery Road traffic. The documented accident rate at the intersection has ranged from zero to
five accidents per year. Traffic volumes at the intersection are moderate with a combined daily trip count for all 4 legs of approximately 6,500 and a peak hourly trip count of approximately
550 for all 4 legs. While the intersection does not meet standard Manual of Uniform Traffic Control Devices (MUTCD) volume or crash warrants for All-Way Stop Control (AWSC), recurring
complaints regarding its unusual alignment and erratic driver behavior prompted Public Works to respond. Consequently, the department commissioned an intersection study with Transportation
Solutions Inc. (TSI), a highly regarded traffic engineering firm. The study determined that an upgrade to AWSC was predicted to lower the crash rate and would be an appropriate interim
step. In the future, TSI recommended that a compact roundabout be considered if funding can be secured. This study was subsequently peer-reviewed by SCJ Alliance, which concurred
with TSI’s findings.
