The study considers the level of phytotoxicity of soils contaminated in a result of the functioning of the objects of the motor transportation complex. The relevance of the work is determined by the amplification of the anthropogenic load on the environment from the road transport infrastructure. The theoretical and empirical methods were used to achieve the goal; the assessment of the pollution level of the urban ecosystems environment by means of the bioindication investigations has been carried out. The theoretical value is represented by the experimental study of the growth processes of test objects on the studied substrates. The proportion of germinated cress seeds and the average height of the ground stem parts of plants were determined for the experiment period. It was found that the growth processes of plants germinated on the soil samples are suppressed compared to the background sample. On the basis of the analysis and statistical processing of data, the phytotoxic effect of the studied soil samples was established. A strong level of soil pollution near the car washes, filling stations and car parks was determined. Experimental studies indicate the need for measures in order to prevent the ingress of harmful substances into the pedosphere and water objects
