Thornton Freeway, opened in 1966, is a major eight-lane radial freeway that primarily serves commuters destined for the Dallas central business district. It was experiencing recurring congestion during both peak commute periods. Average speeds were falling below 30 mph (48 km/h) for extended periods of time in the morning and evening commute. AFTER: Once The Road Zipper System was implemented, average peak hour main lane speeds increased by 86%, from 22 to 41 mph (35 to 65 km/h). Bus passenger volumes increased by 38% in the I-30 corridor and carpools increased by 300% in the morning peak hour from 600 to 1,800 cars. 18 G l e n fi e l d Rd BRIDGES 1 Onewa Rd Shoal Bay As the daily traffic on a bridge In addition to the clear benefits that Auckland increases over time, bridge authorities The Road Zipper System provides • Harbour Bridge Westhaven must find a way to increase the for managed lanes, the system also 1 capacity of the bridge to match the addresses some of the challenges faced 16 16 ay traffic flow.
