Effect in Transportation Systems
Latent demand has been recognised by road traffic professionals for many decades. J. J. Leeming, a British road-traffic engineer and county surveyor between 1924 and 1964, described the phenomenon is his 1969 book:
Motorways and bypasses generate traffic, that is, produce extra traffic, partly by inducing people to travel who would not otherwise have done so by making the new route more convenient than the old, partly by people who go out of their direct route to enjoy the greater convenience of the new road, and partly by people who use the towns bypassed because they are more convenient for shopping and visits when through traffic has been removed.
He went on to give an example of the observed effect following the opening of the Doncaster Bypass section of the A1(M) in 1961.
