The traffic performance of each design concept was evaluated based on v/c ratio and LOS at three locations (where applicable): each interchange ramp terminal on Ehlen Road and at the relocated Ehlen Road/Bents Road intersection.This analysis was performed using SIDRA traffic modeling software to estimate future traffic volumes in 2042. (See TAMP Section 4.2.2 Traffic Performance.) TAMP Table 5-1 summarizes transportation performance of the Preferred Alternative for the 2042 design year. All intersections would perform acceptably and would meet mobility targets, with the ramp intersections having reserve capacity for the future. The County performance standard of LOS D or a v/c ratio of 0.85 is met for the Ehlen Road/Bents Road intersection. The New Dolores Way/Ehlen Road performance is expected to be LOS B or a v/c ratio of 0.78, exceeding the County's performance standard. The Preferred Alternative traffic analysis report is included in TAMP Appendix M. This Policy is met. Policy 8: The County recognizes the role of State Highways and County Arterials as the backbone of the transportation network. These roads are critical for everyday transportation and serve as critical lifelines in emergency situations. The County will support efforts to enhance and maintain the function of these roads through land use policies, access management strategies, and roadway improvements. Ehlen Road is classified as a County Principal Arterial west of 1-5 and an Arterial east of 1-5. The requested action to update the RTSP with the recommendations of the TAMP will support efforts to enhance and maintain this important County facility in the vicinity of the Aurora Donald interchange.This Policy is met. Policy 11: The County recognizes the importance of facilitating freight movement. With this in mind, the strategic routes designated in Figure 7-1 are also hereby designated freight routes. Effort will be made to facilitate freight movement on freight routes. Ehlen Road is indicated as a strategic route on RTSP Figure 7-1 and is a designated freight route. The congestion and safety concerns at the interchange negatively impact the mobility of freight, agricultural goods, and passenger vehicles in the region. Business in the immediate area, including two truck stops/travel centers, are directly impacted by the traffic volumes on the southbound 1-5 off-ramp, the proximity Ehlen Road and Bents Road intersections, and the uphill grades on the on-ramps. The movement of freight through the interchange is compromised by these issues and the resulting traffic back-ups on 1-5. Proposed improvements in the TAMP will address the identified congestion and safety concerns, to the benefit of local businesses and goods movement. This Policy is met. 10.3.3 Bicycle, Pedestrian, and Public Transportation Policies Policy 1: The County will consider the impact County transportation projects have on cycling and pedestrian activities. 1-5:Aurora Donald Interchange(Exit 278)TAMP:Supporting Findings for Marion County Adoption 24
