  • Abstract:
    A basic assumption that must be made whenever one wants to evaluate a proposed system which would replace (in total or in part) the functions presently performed by an existing system or systems, is that the proposed system must perform the replaced functions as well as, or better than the existing system. One should not replace a system (or part of a system) in order to eliminate an existing problem by another system which may eliminate the original problem but possibly may create others whose sum total is equal or greater than the original existing problem. In order to avoid this dilemma, one should systematically look at the total overall systems in question to determine what effects the changes may nave on the total transportation picture. One can first begin by examining the various components of the existing highway plant and the present requirements for travel on it. (See Part III of this paper for selected data of this type). One can next look into and examine the existing and proposed vehicle systems performance characteristics. (See Part II of this paper for selected data on vehicle performance characteristics of both the internal combustion automobile and the electric powered automobile). The next step is to eliminate the large number of uncertainties about the proposed system by first fixing the problem in a given time reference, and with a given problem it must meet. For the purpose of this discussion we have therefore chosen to basically analyse what is presently (or within say the next five years) possible with respect to electric cars and to estimate what part of the existing automobile travel could be replaced. The first part of this report (Part I) therefore attempts to discuss some of possible benefits and deficiencies which might accrue on the total highway transportation system if the electric powered vehicle were developed for use in the near future. The major parts of a transportation system which are discussed are: 1) the vehicle system, (see Part III), 2) the support system, and 3) the command and control system. In addition to these, a change in part of a system also may affect the total system safety, comfort and convenience, and cost. Let us now examine the electric car on a total system basis and try to postulate how it may effect these various major and minor components systems of the total system.
