In Glasglow, Scotland, ITS evaluation reports show that ramp metering can improve freeway capacity by 5 to 13 percent.
In the area of network and traffic management, the results of a ramp-metering trial (TABASCO project, in Glasgow Scotland) indicated that 59 percent of the drivers found ramp-metering very helpful or fairly helpful. The system had a positive impact on the capacity of the motorway (increase by 5 percent) and on the urban diversion routes (increase 13 percent), a decrease in capacity in the urban network (3 percent) and an overall positive impact on the total network (increase by 2 percent) for the afternoon peak (4-5 PM). In the case of an integrated approach, whereby the adjacent urban network is controlled with the IN TUC strategy and the VMS (Variable Message Sign) advice on alternative routes, these figures show a further improvement (increase in capacity of the urban diversion route of 6 percent).
