Collecting traffic flow data is essential for most traffic studies to analyze and evaluate the performance of systems that provide safe trips for people and goods on highways. There are several methods for collecting traffic data. The moving car method (MCM) calculates traffic volume, speed, and travel time simultaneously, while stationary methods, such as camera recordings or radars, observe these data separately. This research aims to use both data collection methods on six segments of urban multi-lane highways to determine the accuracy of the moving car method compared to traditional methods. Additionally, it seeks to model a relationship between these methods to facilitate data collection using MCM for more accurate results. The results indicate no significant difference between the two methods, as the T statistic is less than the critical T in the t-test results. The models show low values of RMSE for the relationships between observed volume, arithmetic and harmonic mean speed, and arithmetic and harmonic means of travel time obtained by stationary methods and these data calculated by MCM. These models can be used with MCM for the study area.
