The application of planning and design procedures to the problem of transitstation renovation is described. The process is illustrated by using as an example the 69th Street Terminal in Philadelphia, a complex transit terminal that handles many transfer movements and transit vehicle connections and has a variety of system elements that are badly in need of renovation. The performance of the existing station was evaluated based on selected objectives and criteria and in light of its conformance with current policy guidelines. A series of alternative renovation layouts was produced to improve the processing of passengers by reducing conflicts, trip times, and level changes. These plans included consideration of horizontal and vertical separation, station access for fare collection, passenger volumes on each transit line, and accommodations for the disabled. Each alternative renovation plan was then evaluated along lines similar to those for the evaluation of the existing station. The results indicated the priority of each interest group and showed where conflict existed. The next step in the process is the preparation of detailed architectural and structural design plans and specifications, cost estimates, and a financial plan.

The renovation of transit stations is becoming increasingly important because the cost of new construction has been rapidly increasing while transit has been attracting new riders because of fuel shortages. Major capital investments in most new transit systems, such as those in Baltimore and Buffalo, are being built incrementally. In cities that have existing transit services, particularly Boston, Chicago, New York, and Philadelphia, greater reliance on present systems will be necessary. As newer systems begin to age, they too will be considered for renovation as recycling of transit structures becomes more productive and necessary. Since the public's impressions and acceptance of transportation services depend heavily on the performance of modal interchange facilities, and since travelers generally place greater weight on time spent transferring between modes than on time spent in the vehicle, it is the abrupt transitions and delays at interface facilities that can reduce the service advantages offered by high speeds, frequent service, and advances in line-haul technology. In the case of older stations, these impedances are reflected in deficient designs, deterioration of physical plant, and changes in the public's perception of acceptable services.
