Resumen
Selection of areas for business tourism center (BTC) placement allows redistributing traffic streams and facilitates providing road traffic safety (RTS). The historical part of St. Petersburg sustains a significant traffic load. In order to increase the RTS level, it is necessary to observe the concept of city polycentric development to select the optimal area for BTC placement. BTCs can be a core of new public and business spaces outside the historical center and be of enough quality and attractive enough to be able to meet competition with the development of central districts and to draw a part of the flow of people. The polycentric development concept will allow to partially reducing the load on the city center and this will result in increasing of RTS: reduction of road traffic accident (RTA) risk and road traffic congestion.
