A simple model of passenger transport in the city of Delhi has been developed using a computer-based software called Long Range Energy Alternatives Planning (LEAP) and the associated Environmental Database (EDB) model. The hierarchical structure of LEAP represents the traffic patterns in terms of passenger travel demand, mode (rail/road), type of vehicle and occupancy (persons per vehicle). Transport database in Delhi together with fuel consumption values for the vehicle types, formed the basis of the transport demand and energy consumption calculations. Emission factors corresponding to the actual vehicle types and driving conditions in Delhi is introduced into the EDB and linked to the energy consumption values for estimating total emission of carbon monoxide (CO), hydrocarbons (HC), nitrous oxides (NOx), sulphur dioxide (SO2), lead (Pb) and total suspended particulates (TSP). The LEAP model is used to estimate total energy demand and the vehicular emissions for the base year 1990/91 and extrapolate for the future 1994/95, 2000/01, 2004/05 and 2009/10, respectively. The model is run under five alternative scenarios to study the impact of different urban transport policy initiatives that would reduce total energy requirement in the transport sector of Delhi and also reduce emission. The prime objective is to arrive at an optimal transport policy which limits the future growth of fuel consumption as well as air pollution.
