Slovak government invests into the development of highway network. The country is hilly, so the development costs are higher than average. EU funding is involved in financing. To release next funding JASPERS in Vienna asked National Highway Authority (NHA) of Slovakia to make O/D research of current traffic flow in 5 major Slovakian cities. We have been called by NHA to supply the design of traffic measures/organization, get the permission for each site by Police of Slovakia; record replies at O/D and purpose of the journey questions while stopping the cars and finally make the interpretation report. Officers of Jaspers from Vienna office have been involved in regular negotiations as well.
