Unformatted text preview: the gap at the 2nd merge sign; 100 ft, 200 ft, 300 ft, 400 ft after the 2nd merge sign; at the 3rd merge sign; 50 ft, 100 ft, 150 ft, 200 ft, 250 ft, 300 ft, 350 ft, 400 ft, and 450 ft after the 3rd merge sign to approximate driver behavior. 84 DRIVING LANE Assumptions Truck Arrive to the station at the taper PASSING LANE Car Truck Arrive to the station at the taper Arrive to the station at the taper NO NO NO D Truck Car Explanations: Car Arrive to the station at the taper Number of Entities Waiting at the Taper for Lane Changing < = 3 Entities arrive to the station at the beginning of the left lane closure taper YES A 3 < Number of Entities Waiting at the Taper for Lane Changing < = 5 YES 5 < Number of Entities Waiting at the Taper for Lane Changing < = 10 YES B C Figure 23: Flowchart of the ARENA Traffic Simulation Model (continued) Entities on the passing lane first check if there are vehicles waiting at the beginning of the left lane closure taper. According to the number of vehicles waiting at the taper, entities check for different gap availability for lane changing. 85 DRIVING LANE PASSING LANE Assumptions Explanations: Truck Truck A At the Beginning of Left Lane Closure Taper NO Car A Car At the Beginning of Left Lane Closure Taper Driving Lane Speed > 75 ft/s YES NO NO Lag Gap in Driving Lane >= 185 ft NO 75 ft/s >= Driving Lane Speed > 55 ft/s NO NO 55 ft/s >= Driving Lane Speed > 35 ft/s 35 ft/s >= Driving Lane Speed > 10 ft/s NO NO Lag Gap in Driving Lane >= 95 ft Hold until finding available Gap NO YES NO Lag Gap in Driving Lane >= 150 ft YES NO YES NO YES 55 ft/s >= Driving Lane Speed > 35 ft/s NO YES Lag Gap in Driving Lane >= 120 ft 75 ft/s >= Driving Lane Speed > 55 ft/s NO YES NO Lag Gap in Driving Lane >= 140 ft NO YES Driving Lane Speed > 75 ft/s YES 35 ft/s >= Driving Lane Speed > 10 ft/s NO NO Lead Gap in Driving Lane >= 55 ft YES Lead Gap in Driving Lane >= 140 ft YES YES Lead Gap in Driving YES Lane >= 105 ft YES Lead Gap in Driving Lane >= 95 ft YES YES Lead Gap in Driving YES Lane >= 75 ft YES Merge to Next Station on Driving Lane Figure 23: Flowchart of the ARENA Traffic Simulation Model (continued) If less than 3 entities with transporters are waiting at the taper, check for the speeds and when the specified gap is available in the driving lane, merge to the driving lane; else wait in the queue until finding available gap for lane changing. 86 DRIVING LANE PASSING LANE Assumptions Explanations: Truck Truck Car Car B At the Beginning of Left Lane Closure Taper NO B At the Beginning of Left Lane Closure Taper Driving Lane Speed > 75 ft/s NO NO 75 ft/s >= Driving Lane Speed > 55 ft/s NO NO 55 ft/s >= Driving Lane Speed > 35 ft/s NO NO 35 ft/s >= Driving Lane Speed > 10 ft/s NO NO Lag Gap in Driving Lane >= 90 ft Hold until finding available Gap YES NO Lag Gap in Driving Lane >= 175 ft YES NO YES NO Lag Gap in Driving Lane >= 140 ft YES NO YES NO YES 55 ft/s >= Driving Lane Speed > 35 ft/s NO YES Lag Gap in Driving Lane >= 110 ft 75 ft/s >= Driving Lane Speed > 55 ft/s NO YES Lag Gap in Driving Lane >= 130 ft Driving Lane Speed > 75 ft/s YES 35 ft/s >= Driving Lane Speed > 10 ft/s NO NO Lead Gap in Driving Lane >= 45 ft YES Lead Gap in Driving Lane >= 130 ft YES YES Lead Gap in Driving Lane >= 95 ft YES YES Lead Gap in Driving Lane >= 85 ft YES YES Lead Gap in Driving Lane >= 65 ft YES YES Merge to Next Station on Driving Lane Figure 23: Flowchart of the ARENA Traffic Simulation Model (continued) If less than 5 entities with transporters are waiting at the taper, check for the speeds and when the specified gap is available in the driving lane, merge to the driving lane; else wait in the queue until finding available gap for lane changing. 87 DRIVING LANE PASSING LANE Assumptions Explanations: Truck Truck C At the Beginning of Left Lane Closure Taper NO Car C Car At the Beginning of Left Lane Closure Taper Driving Lane Speed > 75 ft/s NO NO 75 ft/s >= Driving Lane Speed > 55 ft/s NO NO 55 ft/s >= Driving Lane Speed > 35 ft/s NO NO 35 ft/s >= Driving Lane Speed > 10 ft/s NO NO Lag Gap in Driving Lane >= 80 ft Hold until finding available Gap YES NO Lag Gap in Driving Lane >= 165 ft YES NO YES NO Lag Gap in Driving Lane >= 130 ft YES NO YES NO YES 55 ft/s >= Driving Lane Speed > 35 ft/s NO YES Lag Gap in Driving Lane >= 100 ft 75 ft/s >= Driving Lane Speed > 55 ft/s NO YES Lag Gap in Driving Lane >= 120 ft Driving Lane Speed > 75 ft/s YES 35 ft/s >= Driving Lane Speed > 10 ft/s NO NO Lead Gap in Driving Lane >= 35 ft YES Lead Gap in Driving Lane >= 120 ft YES YES Lead Gap in Driving YES Lane >= 85 ft YES Lead Gap in Driving Lane >= 75 ft YES YES Lead Gap in Driving YES Lane >= 55 ft YES Merge to Next Station on Driving Lane Figure 23: Flowchart of the ARENA Traffic Simulation Model (continued) If less than 10 entities with transporters are waiting at the taper, check for the speeds and when the specified gap is available in the driving lane, merge to the driving lane; else wait in the queue until finding available gap for lane changing. 88 DRIVING LANE PASSING LANE Assumptions Explanations: Truck Truck D At the Beginning of Left Lane Closure Taper NO Car D Car At the Beginning of Left Lane Closure Taper Driving Lane Speed > 75 ft/s NO NO 75 ft...
