Traffic Counting

The automatic counting of traffic on the main road network of the Federation of Bosnia and Herzegovina has been done since 2005. The first printed publication "Traffic Counting on Main Roads of the Federation of Bosnia and Herzegovina in 2006" was published in 2007.

Counters of the French company Sterela and the Slovenian company Mikrobit, i.e. automatic counting devices types QLD-6CX and TLCD 10, are installed around the Federation of Bosnia and Herzegovina. Both types of automatic counting devices use a couple of bidirectional inductive loops. These counters classify vehicles by time intervals, group of vehicle and speed intervals. The difference in classification is that Sterela automatic counters classify vehicles by length, while Micro bits counters do that by inductive print.

TYPE OF VEHICLES COUNTED BY AUTOMATIC COUNTING DEVICES QLD-6CX AND QLTC 10

Type of vehicle	Vehicle description - QLD-6CX	Type of vehicle	Vehicle description - QLTC 10
A1	Motorcycles	A0	Motorcycles
A2	Passenger cars	A1	Passenger Cars and Passenger Cars with Trailers
A3	Passenger Cars with Trailers	A2	Vans
A4	Vans with and without trailers	B1	Light Trucks
B1	Light Trucks	B2	Trucks
B2	Trucks	B3	HGV
B3	HGV	B4	Trailers
B4	Trailers and Tow Trucks	B5	Tow Truck
C	Buses	C1	Buses
		C2	Articulated Buses

With some counters, data on counted vehicles are downloaded via a remote GSM modem, while with the others they are manually collected on the spot and further downloaded by computer equipment.

In addition to these automatic counters, two radar counters are in use as of 2009. Radar counters record the vehicle class, hour and second of vehicle passing.

Vehicles are classified in five categories as follows:

• K1 i K2  – motorcycles, passenger cars and caravans,
• K3  – vans and light trucks,
• K4  – buses and heavy goods vehicles,
• K5  – trailer and tow trucks.

Database of traffic counting contains a counter code (i.e. loop counters have a code of 501 and further, while the radar counters carry the code 600 and further). These counters register the time of recording (hour/ year), the direction of movement of the vehicle, the number and structure of the vehicle, the number of vehicles per length (or type of vehicle), and the speed of the vehicle per selected speed intervals
