Practical requirements for advanced public transportation systems. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

Urban transportation alternative are analyzed and it is shown that public transportation can be competive in speed and convenience with the automobile. A comparison of direct community financial costs for transportation systems is given to illustrate that a bus system offering good service is more expensive than the automobile-based system but that a simple automatic system could produce substantial savings.
