Tiivistelmä: This dataset includes information on Traffic Risk Zones. While dangerous substances are transported on highways there is an eminent risk for environmental pollution, when road tankers are involved in traffic accidents. Also on railroads tank carriages can get derailed causing environmental risks. In these situations the damage caused for environment and eventual spreading of substances depend greatly on local environmental conditions. Environmental conditions having an impact on the severity of the damages include the permeability of the soil, the depth of the ground water in relation to the surface soil, inclination angle of the terrain and water bodies at the location. When risk assessments are done for transportation networks, environmental conditions in proximity of roads are carefully inspected. The risk classification has four main categories and each of the main categories has three sub-categories. Each category has certain physical conditions and pollution risks described as follows: Soil classes A, B and C are determined based on the soil quality and local topography. Class A includes gravel and sand areas, having good permeability and poor retention of liquids. The rough parts of eskers and terminal moraines belong to this category. The risk for ground water contaminations is especially high in the class AI. Class AIII represents the joining areas of ground water bodies, where liquids can flow along the ground water flow or surface water flow to the ground water basin. Rocky areas and cliffs bordering to the ground water areas are classified to this class. Areas having a particle size similar to fine sand belong to B-class. This class has a moderate permeability, and soil can retain some liquids. Areas included in this class are e.g. the borders of ground water areas and sandy moraines. The ground water pollution risk is similar to the class A. A- and B- area’s classes I and II are separated by the ground water level. If the groundwater is less than 6 meters below surface soil the area belongs to AI class. Areas, where the ground water level is deeper than six meters, belong to the AII class. This classification based on 6 meter limit reflects the available technology used to mitigate the pollution damages on ground water areas. BIII areas are gradient areas so they include moraines and rocky areas. Liquids spilled on the BIII areas will most likely flow according to the gradient so that the pollution risk focuses on the water passages, surface waters or water absorption plants along the gradient. Class C includes areas with dense soils and poor permeability. These include also the peat lands and artificial surfaces. CI class includes clay soils near ground water areas, when there can be confined aquifers running under the low permeability clay layers. CII class is common in urban areas and on highways, including the artificially sealed areas (crossings, traffic lines) as well as gently sloping or flat clay, silt and fine-grained moraines. C-class represents relatively low pollution risk areas; the greatest risk being the contamination of ground waters in CI areas. Class W differs from the other main classes. In Class W areas the pollution risk is concentrating on surface waters. In class W the driftin of dangerous substances can be fast; pollutants can end directly to the surface waters or flow through open water passages. Class WII represents exposed ground water sources including closed ground water bonds on eskers. The aim of the risk classification is to give one risk class per part of the road. However, in some cases it is justified to give two parallel classes for the same part of the road. Typical such situation is a ground water area with open water passages. Depending on the situation the pollution risk can concentrate on the open water, ground water or both at the same time. If the permeability of the soil is low e.g. due to the frost or high liquid amount, the risk for open water pollution can be higher than risk for the ground water pollution. The Finnish title of the dataset is: Liikennealueiden ympäristöriskiluokitus.

Laatutiedot
Historiatiedot: The traffic risk classification dataset has been produced as part of a VAKSU-project led by the Ministry of Transport and Communications. During the project was launched also a www-service for planning the transportation routes for dangerous substances. The risk classification has been done in four parts by Maa ja Vesi Oy. ArcSDE-database, including all risk classifications from different years has been modeled and maintained in Finnish Environment Institute. The dataset includes also information on protection techniques used for ground water areas by the Tiehallinto (Finnish Transport Agency).
