The investigation of the M3 motorway section between Polgár and Barabás was performed by various phases. The possible options of alignment took into consideration the area and infrastructure development plans, giving the pros and contras of each option.Years of working had resulted in the alignment zone where it was reasonable to route the motorway section, and where a wide-scale traffic investigation had to be done for the region – for the road sections belonging to the attraction zone of the motorway.

Taking matrices of the National Road Network Model as a basis, the traffic precast for two time-ranges was performed by validation according to the screen line traffic counts. The computer aided investigation was done with the EMME/2 traffic engineering software, which gave data for both of the WITH and WITHOUT cases of implementing the motorway, and demonstrated difference in traffic volumes between the WITH and WITHOUT cases as well. (A detail of it can be seen on the figure above.)
