Introduction
1.1. Traffic Survey:
Traffic engineers and planners need information about traffic. They need information to design and manage road and traffic system. They use the information for planning and designing traffic facilities, selecting geometric standards, economic analysis and determination of priorities. They use this to justify warrant of traffic control devices such as signs, traffic signals, pavement markings, school and pedestrian crossings. The also use this information to study the effectiveness of introduced schemes, diagnosing given situations and finding appropriate solutions, forecasting the effects of projected strategies, calibrating and validating traffic models. Transportation system is a dynamic system. Information about traffic must be regularly updated to keep pace with ever-changing transportation system. Data must be collected and analyzed systematically to get representative information.
Traffic surveys are the means of obtaining information about traffic. This is a systematic way of collecting data to be used for various traffic engineering purposes.
1.1.a. Main purposes of traffic survey: The main purposes of traffic survey are: traffic monitoring, traffic control and management, traffic enforcement, traffic forecasting, model calibration and validating etc.
1.1.b. Parts of traffic studies: Traffic studies include:
Inventory of road traffic physical features
Traffic stream characteristics- volume, speed, density, occupancy studies etc.
Capacity studies of streets and intersections
System usage studies- Travel time and delay, O-D survey
Travel demand- home interview survey
Road users cost- Value of travel time, vehicle
