The present paper focuses on development of trip distribution model for Thiruvananthapuram Municipal Corporation, which is a part of the capital of Kerala state, India. Based on household interview, travel details of the resident population were obtained and base year Origin–Destination matrix was determined; mode-wise and purpose-wise. Toward developing a trip distribution model, a doubly constrained gravity model was attempted, with travel time between zones as the impedance. Exponential and inverse functions were attempted to calibrate the model, in a purpose-wise manner. Trip length distribution and cumulative trip length distribution were plotted for the calibrated models to arrive at the best fit. A comparison was also made between the observed average trip length and estimated average trip length. It was seen that inverse function works better for total trips, work trips and education trips whereas exponential function holds good for non-mandatory trips viz shopping trips, social and medical trips.
