Traffic & Transportation
Manual Counts provides information on the composition of the traffic (any vehicle class configuration), the time of day and the magnitude of the peak period traffic, directional splits and detail vehicular movement volumes. Counts are usually conducted for periods less than 24 hours and can also include pedestrian movements, traffic queues and delays.
Automatic Electronic Counts are conducted when information is required on vehicular movement for periods exceeding 24 hours, utilizing intrusive as well as non-
Cordon Counts are used to establish the traffic flow into, through and out of predefined areas as well as the time spent within such areas. These counts can be done manually, through electronic data collection (video) or by means of number plate surveys.

Speed Surveys are conducted at specific locations for establishing the speed characteristics of the entire traffic streams at such locations.

Traffic Queue and Delay Surveys provide valuable information on the length of queues at intersections and the amount of delay experienced by road users due to road, traffic characteristics, intersection saturation flow rates and total traffic delays.
In line with the requirements of the new SARTSM Vol. 3, applicable to all SADC countries, queue lengths are required to establish the warrants for signalisation of intersections.
Roadside Interviews can provide valuable information on the perception of road users, their needs and requirements as well as the characteristics of drivers and vehicles.
The use of loops (temporary or permanent) includes applications such as traffic counting, speed measuring and prosecution, headway and gap measuring, traffic signal control activation or green time extension and parking access and management control.
