3.1. TRIP GENERATION
Trip generation is the first step in the conventional four-step transportation planning process, widely used for forecasting travel demands. It predicts the number of trips originating in or destined for a particular traffic analysis zone [4].
Trip generation uses trip rates that are averages for large segment of the study area. Trip productions are based on household characteristics such as the number of people in the household and the number of vehicles available [1]. For example, a household with four people and two vehicles may be assumed to produce 3.00 work trips per day. Trips per household are then expanded to trips per zone. Trip attractions are typically based on the level of employment in a zone. For example a zone could be assumed to attract 1.32 home based work trips for every person employed in that zone. Trip generation is used to calculate person trips.
Here in this stage, trip production and trip attraction after 10 years (2011) is determined (base year 2001). To do this at first existing trip production and attraction parameters are calculated using growth rates after 10 years (Table 1). These growth rates have been assumed on country aspect [5 and 6]. Now using Table 1, tables 2 and 3 have been generated. For details calculation please go through Appendix A-D (Supplementary File).
