The E263 (2) and E77(A2) are roads respectively connecting Estonia and Latvia to the Russian border and Pskov (RU). They both have 2+2 motorway sections with very high traffic density near Tallinn and Riga. They are one of most intensively used road sections connecting ports, logistic centres and they connect capitals with Eastern regions. More mild climate with dynamic speed management allows significant time-savings due increased speedlimits in winter period when road conditions are safe. The growing transit truck traffic is seen as a critical player in traffic safety, more truck drivers from the Southern part of Europa are involved with minimal experience of winter driving causing an increasing number of traffic accidents. Smart weather responsive traffic management solutions create new possibilities to communicate with roadusers to warn them about severe weather risks and to inform them on safe winter driving.
The project SMART E263/E77 coo-financed by the Centralbaltic Cross-border Cooperation Programme 2014-2020 will implement smart dynamic weather responsive traffic management solutions in close cooperation between Estonian and Latvian national road operators by sharing knowledge and developing new joint approaches. The cooperation with the national traffic management centres will enable pro-active cross-border traffic management.
The Estonian, E263 Tallinn-Tartu-Võru-Luhamaa road will have smart dynamic speed management (up to 110 km/h) in Tallinn-Kose 2+2 section km 6-40 and E263 section between Mäo and Luhamaa will be equipped with warning VMS signs to insure in-site critical road information delivery. In LV, E77 (A2) Riga-Sigulda-Veclaicene road 2+2 motorway section from A4 junction to A3 (30 km section) will be equipped with dynamic speed management (up to 110 km/h). The E77 section between the A3 junction to the Estonian border will be equipped with warning VMS signs to assure in-site on critical road information delivery. It is estimated that all measures taken in Estonia and Latvia will save about 2,46 minutes of travel time per vehicle (0,88% up to 5,6% on 2+2 sections) and will increase traffic safety in Tallinn-Tartu-Luhamaa-Riga transport corridor.
