Abstract: The management of future growth and mobility in urban corridors and areas has been based in part upon use of the Levels of Service and procedures of the Highway Capacity Manual. Capacity Reservation in an urban corridor is a peak hour Growth Management concept which reserves a portion of the at-grade highway laneage for future 'High Capacity' vehicle usage rather than for auto usage. The concept does not specify the character or extent of 'High Capacity' usage, but for Growth Management determinations of existing, and future roadway or corridor Levels of Service with new developments in place, removes one auto lane in each direction from the Highway Capacity Manual auto capacity analysis thus reducing the available Level of Service for autos in the corridor. The corridor is then analized for Capacity determinations using the 'Mass Transit' procedures of the Highway Capacity Manual rather than the auto procedures. Within these particular corridors, the peak-hour growth of development can then be managed with the auto level of service at its optimal level and new person movements form continuing development in the corridor can then be channeled into improvement of the corridor's 'High Capacity' capability through the use of development agreements which affect ridership. Reservation of an auto lane for a higher and better use rather than continuing to dedicate all lanes to the auto should assist urban corridors managed under this philosophy to 'Grow Upward' with modal and density changes rather than continuing to 'Grow Outward' with historical suburbanization and congestion problems. An integral part of this peak hour management concept is the application of person-based rather than vehicle-based movement principles, and a person-based functional classification structure is presented for quantifying and the movement capacity of existing urban corridors and areas as a whole. In addition, a growth management strategy is presented to control the Land Use - Transportation Cycle based upon a relationship between Level of Service, as defined by the frequency of high capacity service, and land use density.
