Tallinn University of Technology's road engineering chair head Ain Kendra said that the current system of road design dates back to the 80s.
In an interview with Eesti Päevaleht today, Kendra said that tires of modern cars have greater pressure, smaller contact area with roads and trucks are heavier, all factors that new roads fail to take into account.
Another problem is a lack of a holistic approach in planning new roads, Kendra said, adding that in other countries, all different types of transport are looked at, for example how the new trains affect the number of cars traveling on certain roads.
Another example, Kendra said, is that when the Lõunakeskus mall in Tartu was opened, traffic volumes doubled on on Riia maantee, which connects the city center with the mall.
Speaking about the nation's road-unfriendly weather, Kendra said that by current standards, water should be diverted from the road from a depth of at least 1.25 meters under the pavement, but many roads fail to do so. Kendra added that recent studies have shown that water as deep as 2-3 meters under the road surface could pose a danger in winter.
