IMPORTANCE OF TEMPORARY TRAFFIC REGULATION DURING CONSTRUCTION OR RECONSTRUCTION OF ROADS

An example of such problem is the South Osijek Bypass, a part of the D2 Croatian state road. With traffic load of 18,500 vehicles/day AADT (Average Annual Daily Traffic), this is one of the busiest roads in Croatia. The role of South Osijek Bypass is traffic redirection outside the city and connection of major roads to Našice (D2) and Valpovo (D36) to the west, Vukovar (D2) and Erdut (D213) to the east, Beli Manastir (D7) in the north and Ðakovo (D7) and Vinkovci (D518) to the south. Northern pavement of South Osijek Bypass was built between 1973 and 1989 year with two traffic lanes intended for two-way traffic while the southern pavement extension was postponed because of, at that point, insufficient traffic volume. Southern pavement construction started in year 2011, during which extension of four intersections and building of a whole one new intersection was needed. Given that the old, northern pavement was constantly under heavy traffic, the solution of temporary traffic regulation during the works was a particular challenge for the designer.
The paper describes traffic solutions for unobstructed traffic flow during construction works on the southern pavement extension of South Osijek Bypass with special emphasis on the importance of quality traffic flows diverting.
