Comparison of Data Collection Methods for Microscopic Traffic Simulation in VISSIM: A Case Study of Spatial Planning in the Złotno District of Łódź

Summary/Abstract: This paper presents a case study on a comparison of data collection methods for the calibration and validation of a microsimulation traffic model in PTV VISSIM software, based on the example of a section of the street network of Złotno in Łódź. The aim of the study was to assess the practical usability and reliability of two data sources: limited field measurements and commercial floating car data (FCD) provided by TomTom MOVE, in the context of traffic modelling for urban planning. Two parallel VISSIM models were built and calibrated, each based on one of the analysed data sources. The GEH-statistic, scalable quality value (SQV), root mean square error (RMSE) and correlation coefficient (CC) indices were used to assess the quality of the fit. The analysis showed that although both approaches can lead to acceptable calibration results, their characteristics and limitations imply the need for an informed choice of data collection method, adapted to the specifics of the area under analysis, the scale of the project and the spatial planning objectives.
