Describe Trip generation, trip distribution and modal split ?

Trip generation refers to the process of estimating the number of trips that will be generated by a particular land use or activity. It involves analyzing various factors such as population, employment, and trip rates to determine the total number of trips that will be made in a given area.

Trip distribution is the process of determining the spatial pattern of trips generated in a particular area. It involves analyzing the origins and destinations of trips and allocating them to different zones or areas within the study area. This helps in understanding the flow of trips and identifying the major travel corridors or routes.

Modal split refers to the distribution of trips among different modes of transportation, such as cars, public transit, walking, or cycling. It involves analyzing the preferences and choices of travelers in terms of the mode of transportation they use for their trips. Modal split analysis helps in understanding the share of trips made by each mode and can be used to evaluate the effectiveness of transportation policies and infrastructure investments.
