DESCRIPTION
Land use distribution and transportation both are very important issue for Dhaka city in recent period. To relate these two issues with each other is also a very effective job but a difficult one indeed. This study intends to find out the impact of different land use changes on the transportation system of Dhaka city. One of the most important roads of Dhaka city, Mirpur Road has been taken to understand and to analyze for this study. This study will help to take significant decisions and generate proper policies in transportation sector. It will also contribute to the attempts of combining land use planning and transportation planning. By assessing the land use change impact on transportation system, traffic management, congestion control and improvement of road network will be possible to makeTRANSCRIPT

Land Use Change Impact(Contd..)
Impact for Development Traffic in 2013 (BRTC Market-Technical)
The average carriage way width of the road is 82.4 which is quite
satisfactory but the peak hourly traffic volume 5351.53 PCU is quite high.
Journey Speed and Spot Speed is deteriorating over the period.
Commercial and Educational land use change is in the dominating position
and Residential land use change is in a negative trend.
Peak hourly traffic volume from the land use is dominated by the
commercial land uses(1445.45 PCU/hr)
The vehicle capacity ratio (v/c) is increasing over the time which indicates
deterioration of the road condition according to the standards of the LOS.
Major Findings
Recommendations
Commercial land uses act as the major point of traffic generation and
attraction for this road, there should be strong restrictions, regulations and
guidelines for establishing any kind of new commercial land use along this
road.
Garments and Educational land use generate and attract a huge amount of
traffic at a specific time which creates a huge pressure on the road in a
certain time period. The establishment of any new Garments and
Educational institution should be strictly prohibited on this road to reduce
the peak hourly traffic flow.
