23 iv Happy Niketan Kolkata Traffic Impact Study 1 INTRODUCTION 1.1 BACKGROUND Project proponent has proposed to construct residential and commercial project. The project comprises of 4891 residential units. On completion, the project will provide 3876 parking spaces within the premises. GMD Consultants has been commissioned by the project proponent to provide a Traffic Impact Study for this project. 1.2 SCOPE The scope of this study is listed below: • Traffic Surveys: To conduct traffic surveys of area project site in order to capture base traffic: o Assess current traffic pattern on access road – neighboring road network o Capture traffic emanating from new developments and from adjacent properties • Traffic Circulation: To review traffic circulation plan considering various types of vehicles users (cars, 2W, fire tender) • Traffic Surveys: To conduct traffic surveys of all roads within radius of 5 km of project area to capture base traffic: • Impact Analysis: Analyze the forecast project traffic in conjunction with base traffic. Conduct an Impact Analysis of project traffic as well as study impacts and suggest mitigation measures. • Swept Path Analysis: Review traffic circulation to ensure proper and efficient traffic movement. Conduct swept path analysis at critical locations of project entry/exit to ensure safe and efficient turning maneuvers. • Junction Analysis: Junction analysis for present (2018) and future scenario (2030) using PTV VISTRO Software • Traffic Control: Address the provision of road signages, markings and traffic calming measures. Also provide a traffic management plan to address issues
