The article examined the possibility of using General Transit Feed Specification (GTFS) to identify deviations of public transport in morning hour traffic. Deviations in the functioning of public transport spanned in a radius of 30 minutes public transport travel time from the center of the city. The adopted travel time to the center is taken from a comprehensive traffic study performed in the city where indicated value of 27 minutes (comprehensive traffic study ...) is used as the average

The results of calculations of time availability were made every 5 minutes and applied to each other and trimmed among themselves. Hence the contour line was established within isochrone of 30 minutes, with the identification of areas with 100% certainty of public transport access to the center of the city and areas of lesser public transport accessibility. The resultant isolines were measured against the population living in census districts, on the basis of which the areas of certain as well as uncertain 30 minute travel time to the center of the city were determined.
