What is Mode Choice Model? Mode Choice models define travelers’ choice towards choosing various modes like public transport or private transport modes. These models take into account all the input variables about each possible mode of transport that the traveler has available for the trip and gives the proportion of travelers which would use each mode of transport. This model sometimes called a mode split model. Mode choice model helps in building trip matrix and mode split model separates this matrix into each mode of transport. These matrices can be assigned to the public transport networks respectively to give flows on each section of each public transport services. Mode choice model also provides probability of individual trip using each…show more content…
Discrete model is based on selecting the alternative that provide highest utility to the choice maker. It is not always possible to predict correct alternative for an individual because some of the variables are unobserved and situational thus the concept of random utility appeared. I early 1970s, discrete choice was used for binary choice of travel mode, later, its use spread to multi choice set as well as in other stages of forecasting process. Since, 1990s, application of soft computing models such as Artificial Neural Network models, Fuzzy logic applications and Genetic Algorithm was adopted. Mode choice analysis helps in engineering, transport planning and policy making process to study existing demand of transportation system and forecast the future needs of the proposed transportation system as when insight of preferences and requirement of commuters are known. Mode choice model is to effectively manage the transport demand and be able to provide for these demands by making changes in the existing system.

The aggregate transport planning models have been severely criticized for their inflexibility and inaccuracy. (Mode choice analysis:The data, the models and future ahead, 2014) In disaggregate approach individual choice responses as a function of the characteristics of the alternatives available and socio-demographic attributes of each individual. This model is more transferable to a different point in time and to a different geographic context, very well suited for proactive policy analysis. (Mode choice analysis:The data, the models and future ahead, 2014) Efficiency of disaggregate approach is more than the aggregate approach in terms of model reliability per unit cost of data collection.
