Analysis of Land Use and Mobility Scenarios for the Reduction of Transport Energy in the Urban Area of Catania

A consolidated approach for pursuing sustainable urban mobility consists of reducing transport energy through three key strategies: a land use distribution lowering the need and length of motorized mobility; adoption of measures favouring low impact transport modes; and incentives for energy efficient vehicle fleets. A simple land use and transport model is presented in this paper to calculate a commuting transport energy indicator able to address the delivery of sustainable urban and transport plans. The model is based on a mathematical description of the transport system and a transport mode choice model following ideal simple rules based on the distance from home to workplace and on zonal transit network accessibility. For each transport mode energy consumption, capacity and load factor are considered. Assignment of flows between home and work zones is formulated as a standard transportation problem to minimize the required transport energy. The model is applied to the urban area of Catania, a medium-sized town in Italy, for three scenarios: 1) improving walking/cycling facilities and accessibility to the existing transit network; 2) adding four Bus Rapid Transit (BRT) lines and one metro line to the transit network; and 3) relocating a fraction of residents around the stations of the metro line. These scenarios reflect some of the main measures of the urban mobility and land use plans which are currently under discussion. For each scenario the authors compute the “Transport Energy Dependence” indicator, the travelled distance and modal share for each transport mode at the urban and traffic zone scales. First results show the methodology is suitable to different aims: to evaluate the potential impact of changes in land use, transport and vehicle technologies policies in terms of transport energy consumption; to define a minimum transport energy as a reference value to be compared with the actual consumed transport energy; and to define transport energy requirements for the approval of land use and transport plans.
