PORTFOLIO MODEL OF RESOURCE ALLOCATION FOR THE TRANSIT FIRM

An agency resource-allocation model is presented that allows a fuller understanding of performance by linking aggregate performance indicators with diaggregated measures of route-level activity. The evaluative framework is based on the portfolio-choice model of financial management. In this model, aggregate return and risk parameters are found by examining the resource-allocation pattern and ridership levels for individual routes. Although this is primarily an economic utility-maximizing approach, the model paramenters were calcualted for two time periods and compared in an evaluation of resource reallocation. Before and after levels of service and ridership counts for 41 routes operated by the San Diego Transit Corporation Provide the inputs to the modeling effort. Results show that the average return increased with minimal risk impacts in the post-reallocation period, indicating a better resource-allocation package. The relationship between resource allocation and the aggregated average return is thus made explicit and the change in aggregate indicators viewed directly as a function of management and operational considerations at the route level. Finally, the model or method of analysis is evaluated in terms of both its conceptual and measurement procedures. (Author)
