MEASURING ENERGY USE IN URBAN TRAVEL USING A SKETCH PLANNING MODEL

An innovative approach to modeling transportation energy demand in metropolitan areas was developed at Argonne National Laboratory for US DOE. A sketch planning travel-demand model (called SRGP) was joined with an auto-ownership model, a fitting technique for demographic forecasts, and an algorithm to assign origin/destination travel to the intervening districts called the Urban Transportation Policy Analysis Process (UTPAP). The central component of UTPAP is XRGP, an extended version of the computer program for the Short Range Generalized Transportation Policy Analysis (SRGP), which is a sequence of disaggregate travel-demand models that estimate aggregate travel demand through a random-sample enumeration process. The CRGP has the extended ability to input different vehicle-ownership profiles for different household types and account for travel by as many as ten vehicle types, fueled by up to seven types of fuel. Results from this analysis process are sensitive to technology characteristics, as well as to fuel price and metropolitan development patterns. Forecasts for three typical cities indicate a large potential for saving energy relying on automotive fuel-economy improvements and rising fuel prices, without detrimental effects or urban mobility. Fuel-saving potential varies by type of city, with rapidly growing metropolitan areas unlikely to stay below 1980 fuel use unless population growth occurs in more-established, transit oriented cities. Diesel-fuel use may continue to rise after 1990, depending directly on the strength of the economy and inversely on the success of competing, spark-ignition/gasoline-fueled automobiles.
