The article presents the results of studies on the comparison of intraurban transport accessibility of the city of Łódź in the light of the theoretical and real transit times of individual car transportation. Article adopts both methodological and cognitive objectives. The first one is the evaluation of the data usefulness in geography of transport and especially in studies focusing on transport accessibility. The second objective focuses on examining diversification (including spatial) of differences in transit times resulting from the adoption of the theoretical and real-time approaches. Data on the theoretical transit times are calculated based on assumption that the motor vehicles move along the street network with the maximum speed permitted by law, with the exclusion of all other variables. The second source of data (real-times) is a service Distance Matrix Responses provided by Google Maps APIs. By using isochronic method, it was found that the data collected from the Google servers are highly useful for research in the field of geography of transport, including analysis of transport accessibility. However, patterns revealed by the data can not be utilized uncritically and used for any analysis. With respect to the cognitive objective, it was found that the diversification (including spatial) of differences in transit times resulting from the adoption of theoretical and real-time approach in relationship to reference points in the city of Łódź is significant.
