Peter, my dear fellow! %) The agencies involved have absolutely no incentive to address the problem - Their very existence depends on the gridlock - The municipalities cooperate by allowing development which outruns road capacity in multiples, the road-builders use the snarl to get public support for construction bonds for projects which will be tied up in court for 20+ years, and feast on the float in the interim - Everybody's happy, except the chumps in the cars... Since others have alluded to the "science" of traffic management, it is a fact that the supply of vehicles increases faster than carrying capacity of the roads, most places - Certainly here in the PRC. This has been studied to death, and the obvious ramifications being unpalatable, resolutely ignored. best regards, Jack -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
