Vilnius city Municipal Transportation Strategy

Currently, the Vilnius city center is crossed by highways and the city has no beltway or ring-road. Large traffic flows in the central parts of the city have resulted in severe traffic congestion and diminished the popularity of public transit.

Traffic and passenger flows can be concentrated, while creating optimal conditions for public transportation in Vilnius by fully completing a beltway around the city and building PINAVIA junctions, parking facilities and public transit terminals at its main intersections. Additionally, by creating new jobs at easily accessible locations on the city’s periphery (within PINAVIA junctions) and instituting traffic restrictions in central parts of the city, the problem of traffic congestion can be solved without any additional infrastructural changes.

Investments

Building a PINAVIA junction for different categories of roadways (Ellipse) with projected speeds of 50 and 70 km/h, instead of a Cloverleaf interchange, we would save 7 ha of land. By investing approximately 9 million EUR, and following the sale of commercially zoned land at the center of the junction for the same amount as its purchase price, we would arrive at a final construction cost of 8 million EUR. A Cloverleaf interchange would cost approximately 13 million EUR. Thus, an elliptical PINAVIA junction is one-third the price of a Cloverleaf interchange.

Building a PINAVIA for a projected speed of 60 km/h, instead of 4-level junction, while investing approximately 30 million EUR, and following the sale of commercially zoned land at the center of the junction for the same amount as its purchase price, we would arrive at a final construction cost of 25 million EUR. The approximately 50 million EURO investment required for the construction of a 4-level junction would be unmet. Thus, the investment required for one 4-level junction can be used to build two comparable PINAVIA type junctions

In those events when the construction of a PINAVIA junction requires larger investments than the cost of a Cloverleaf interchange, it is important to note that investments make a speedy return in a just a few years of operation due to greater capacity, traffic safety and the infrastructure located at the junction’s center.

Crucially, the very construction of a PINAVIA junction may in many cases be profitable in of itself due to increased value beyond that used in calculations of the commercially zoned land at its center, which results from excellent access from all directions to the facilities therein.

The economic effect of a PINAVIA junction with greater projected speeds is increased due to the possibility to use a larger area of the center in comparison to the overall area of the junction and roadway.
