Modeling Assumptions RCTC Existing weekday morning modeled (Monday to Thursday) • Volumes constant in all scenarios – same GP, same Express • EL utilization: truly will re-balance if GP conditions improve • Corridor traffic: should expect an overall increase • Allows for an apples to apples view of all scenarios • GP vehicles will use weave lanes if unrestricted •

Westbound Traffic Flow Options RCTC Option 1 improves GP • lanes Degrades Express Lane • Aux lane increases GP • capacity New bottleneck at SR • 241 EL lanes become a • “free for all” 71 still a bottleneck GP Aux improves capacity New bottleneck at 241 EL lanes are a free-for-all Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Existing 10,600 16 mph 43 mph 59 mph 5 hours Option 1 11,900 26 mph 22 mph 34 mph 2.5 hours

Westbound Traffic Flow Options RCTC Option 2 improves GP • lanes – extra 500 vph of throughput Degrades Express • Lane: EL egresses upstream of the bottleneck Limits EL egress • capacity New bottleneck forms • Fewer GP to EL vehicles – at SR 241 Still a hot spot better GP flow EL ingresses earlier – Egress higher utilization of EL congestion Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Existing 10,600 16 mph 43 mph 59 mph 5 hours Option 2 11,100 15 mph 56 mph 59 mph 4.5 hours

Westbound Traffic Flow Options RCTC Option 3 improves GP • lanes Degrades Express Lane • Allows earlier ingress, • later egress, and GP queue jumpers = equity between GP and weave lane Limits EL egress • capacity New bottleneck Still a hot spot New bottleneck forms • at EL Egress EL to GP GP to OC EL GP traffic leaves later jumps in earlier queue jumps Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Existing 10,600 16 mph 43 mph 59 mph 5 hours Option 3 11,800 22 mph 52 mph 59 mph 3.5 hours

Westbound Traffic Flow Options RCTC Option 4 improves • GP capacity Maintains EL • capacity New bottleneck • forms at SR 241 Overall duration of • congestion reduced. Still a hot spot New bottleneck Egress congestion Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Existing 10,600 16 mph 43 mph 59 mph 5 hours Option 4 11,900 23 mph 23 mph 59 mph 2.5 hours

Westbound Traffic Flow Options RCTC Option 4b – • removing ramp- Still a hot spot New bottleneck meter at Green River Road improves ramp throughput Upstream GP overall • Egress slightly more congestion congested. Other factors: • Remove Green River Ramp meter Ramp merge – 3 to 2 to 1 • Still a hot spot New bottleneck lane. Benefits in other • scenarios? Higher throughput Egress congestion Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Option 4 11,900 23.4 mph 23 mph 59 mph 2.5 hours Option 4b (No 12,000 22.7 mph 22 mph 59 mph 2.5 hours ramp meter)

Westbound Traffic Flow Options RCTC Similar to Option 4, • slight overall improvement Clears overall • congestion 15 minutes earlier New bottleneck Still a hot spot Egress congestion Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Existing 10,600 16 mph 43 mph 59 mph 5 hours Option 5 11,700 24 mph 20 mph 59 mph 2.5 hours

Westbound Traffic Flow Options RCTC Option 6 • improves GP lanes Degrades • Express Lane New bottleneck GP queue jumpers Egress Early ingress congestion Scenario Global GP Speed: I-15 to GP Speed: Green RC EL to OC EL Duration of Throughput County Line River Rd Ramp to Congestion 241 Existing 10,600 16 mph 43 mph 59 mph 5 hours Option 6 11,900 27 mph 21 mph 47 mph 2.5 hours
