Part of: Site Impact Traffic Assessment: Problems and Solutions


The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes the foundation of any site impact analysis. Presently, there is no uniform procedure to collect and validate the existing traffic data which is used to determine the existing Level of Service and traffic forecasting (cumulative traffic). This paper presents a cost effective data to conduct site impact analysis. Other important aspects covered are the field evaluation procedure, personnel used for data collection, and quality control of collecting traffic data for site impact analysis.
