Sound pollution and traffic jam are two major problems in most of the city roads of developing cities like as Dhaka, Bangladesh. Traffic jam, as well as mixed traffic condition, is the major cause of sound pollution in the city roads. Both of these issues affect mostly on country's public health and development. A lot of new roads have been constructed in Dhaka city every year but the majority of the roads have not been constructed considering the future AADT (Annual Average Daily Traffic) value. The traffic volume has increased a lot as the population of the country increased rapidly and shifting the status of the country from developing county to the developed country increased the demand for privet car and as a result traffic jam is a regular problem in the Dhaka city. Due to increasing traffic volume, the waiting time in the traffic jam has been increased consequently. Drivers bell the horn of their vehicle to attract the concentration of the traffic police so that the traffic police provide the green signal to his/her desired destination road. Also after the starting of the green signal or when the yellow signal is provided to the drivers, the driver bell horn of their vehicle so that low-speed vehicle side to high-speed vehicle. Besides these, bikers continuously press the hydraulic horn to provide them free access throughout their road. In this research work, we have attempted to show how much free access is available to Natun Bazar to Farmgate road, a major traffic-congested road in Dhaka city for both directions of traffic movement and also the present sound pollution condition in this road. On an average of 9.06% and 8.46% of a day the driver gets free access [green signal] on this route based on the traffic movement direction [Natun Bazar to Farmgate route]. At present on average it requires around 2 hr. for traveling 7 km road and this is a hotspot of huge time killing for the city people in their regular life. Besides this passenger has to bear a sound level of around 101 dB including the residents living in this area beside the roadway. This impact is tremendous for the bikers and bus passengers result, they are experiencing significant issues such as headaches, decreased job performance, decreased focus, exhaustion, tension, and tiredness.
