Public transport demand model is a fundamental research to plan the transport system for any city. This research aims to develop a model based on SATURN software which is well known as transportation software and able to depict the real scenario. With the assistance of the software a demand model is prepared for Dhaka city, the capital of Bangladesh. To prepare this model, in this research various data are collected which are require by the software and process those data in ArcGIS software and code into SATURN format. After that those coded data are feed in SATURN software and the model has been prepared. From the model the demand for public transport is analysis with the help of several modules and analysis the general flow of public transport, capacity flow of public transport, trip generation and distribution of public transport. From these analysis various situation are found. Commencing these analysis, some discussion are made, these are Mirpur, New market, Dhanmondi, Gulshan 1 &2, Mohakhali, Motijheel, Newmarket, Shahabagh, Farm gate areas have higher flow of public transport than other areas because people employ in these zone and various activity are exist also in these areas. So, there is imbalance of public transport flow in public transport routes and to bus stops. That’s why in future these arenas may cause problems. Some zones have higher demand of capacity in terms of both bus stops and bus routes and some zones have less demand of capacity. These surpluses and deficits should be minimizing. So there is a choice for release surplus and meet deficits. The major main and arterial roads of Dhaka city are aligned with north to south. It may cause problems in future for connecting east to west of Dhaka city. So this problem should consider in future transport planning. Gulshan 1 and 2, Mirpur road, Motijheel, Farm gate, Shahabagh areas have higher demand than other areas because these areas have more activity than others area. There is an imbalance of demand of public transport in terms of both bus stops and bus routes. Reducing this issue can help to attain efficient and effective public transport system. For the future public transport planning of Dhaka city these findings might help. From this model Traffic management measures, signal optimization, demand forecasting can be done if it is modified a bit.
Dhaka city is the capital of Bangladesh and about 16 million people live in this city. There are a significant number of trip production and distribution zones. According to the Dhaka Urban Transport Plan “the bus passenger volume has been estimated as 1.7 million passengers. In the study 1991, the passenger volume was calculated to be nearly 9, 75,000. The Dhaka Urban Transport Plan forecasts indicated a passenger volume of about 2040000 in 2006.” However, no measures are taken to promote bus transport system.
The nation's development and the need to meet mobility, environmental, and energy objectives place demands on public transport systems. In current systems, some of which are old and in need have upgrading, must expand service area, and improve efficiency to serve these demands. Research is necessary to solve public transport demand problems and to introduce innovations into the route demand analysis. Without demand analysis, transport network planning could not occur. Developing realistic estimates of future travel flow of transportation is problematic. Demand analysis model often helps to solve those problems. This demand model includes not only passenger travel, but also the movement of people. To improve our city streets to supply only to the growing needs of the future car travelers might not be feasible with the limited resources. For increasing the capacity of streets, whole line of buildings might need demolition. The limited space in towns might not permit the construction of expressways and superior facilities.
