Singapore made rush hour pay for the roads it was crushing
the problem
Roads jammed at eight, idle at ten
background
By the early 1970s Singapore's central business district was gridlocked every weekday morning: a small island nation with no room to sprawl, rising car ownership, and virtually all commuter traffic converging on the same few square kilometers between 7:30 and 9:30 am. Roads built for a smaller city now carried far more cars than they could move, and congestion was starting to look like a permanent tax on the economy.
The obvious fixes were both unavailable. Building more roads meant demolishing scarce, expensive urban land earmarked for housing and commerce. Banning cars outright was politically and economically untenable — car ownership was a marker of the growing middle class, and a blunt ban would have hit essential trips as hard as discretionary ones. Planners needed a way to shrink the crowd without shrinking the road or removing the cars entirely.
the move
The Area Licensing Scheme, launched 2 June 1975 by Singapore's Ministry of Communications, required drivers to buy a supplementary paper license to enter a cordoned-off 'Restricted Zone' in the CBD during the morning peak; in 1998 the by-then-formed Land Transport Authority replaced it with Electronic Road Pricing, automated gantries that vary the toll by time of day, vehicle type, and road segment to keep traffic moving at a target speed.
the payoff
Traffic entering the Restricted Zone in the morning peak fell from about 32,500 to roughly 7,700 vehicles in the weeks after the June 1975 launch — a drop widely cited at around 76%, far beyond the government's original 25-30% target — with transit's share of CBD-bound work trips climbing from about 33% before the scheme to roughly 70% by 1983. Manual enforcement and flat time-of-day pricing persisted until the 1998 move to Electronic Road Pricing made charges dynamic and gantry-based.
what came after
The Area Licensing Scheme is widely credited as the world's first successful urban congestion-pricing scheme, and its 1998 Electronic Road Pricing successor became the reference model cited when London designed its 2003 congestion charge and when Stockholm and other cities later built their own cordon and dynamic-pricing systems.
