Singapore appears as a reference point in the book’s discussion of traffic congestion and congestion pricing. The available account directs readers to studies and reporting on Singapore’s traffic system, but provides no concrete details about the policy’s design, implementation, or effects.## Sources on the Traffic System The book points to Dan Baum’s account of Singapore’s traffic system, alongside research by Rex Toh and Sock-Yong Phang on curbing urban traffic congestion and a report by Teo Poh Keng on a toll system Singapore planned to adopt. These references place Singapore within a wider examination of how road pricing might address urban traffic, but the cited passage does not recount particular measures or results.## Place in the Book’s Argument Singapore serves here as a case for further reading rather than a developed narrative example. The book’s references connect it to congestion pricing, while the available evidence leaves open how the system worked and what consequences it produced; claims beyond that connection would exceed the account supplied.
