Traffic Volume Survey Types:
Manual Count Surveys: Using checklists or tally counters, observers manually count the number of cars at a given location. This approach may involve classifying vehicles according to their kind, such as cars, trucks, and buses.

Automatic traffic counters: Pneumatic tubes, inductive loops, and infrared sensors are examples of electronic devices that automatically record traffic volume. These are frequently employed for ongoing, long-term surveillance.

Cordon counts: are used to count the number of cars coming into or going out of a specific area, usually a city or commercial center. This is typical for urban planning traffic flow studies.

Screen Line Counts: These polls track movement along a virtual line that crosses several streets. Analyzing the distribution of traffic in a given area is the aim.
