Time deviations in the operation of public transport providing access to selected services in the city of Szczecin

The article presents issues related to public transport time accessibility to some selected services, including indoor swimming pools, cinemas, hospitals and shopping centres. In order to measure the above-mentioned accessibility the short distance method was used in the following time periods: 7:00-9:00 am for the hospitals; 5:00-7:00 pm for the shopping centres; 6:00-8:00 pm for the cinemas and 6:00-8:00 pm for the swimming pools. For each time period the measures were taken every 15 minutes. The main purpose of the article is to determine temporal accessibility for various purposes, the number of people living at a certain time distance and the diversity of accessibility by public transport. The public transport accessibility to the selected services indicates areas where the accessibility is limited. Time deviations in the operation of the public transport were calculated for all the selected time periods. The results of both measurements and calculations are presented in graphic form. Moreover, the graph includes the number of Szczecin citizens living in different time accessibility areas and in places with the highest time deviations.
