The advancement of information technology and available online data sources have made it possible to review and eva‎luate the transportation network from different perspectives. These big data have reliability and spatial and temporal resolution needed for use with network eva‎luation purposes and overcome the weaknesses of traditional data used in most past studies. This type of data has a dynamic nature and it is possible to update and collect them at different times in the future. The purpose of this research is to develop a framework for using new data obtained from online traffic platforms in order to eva‎luate and compare the performance of the transportation network of cities from the point of view of mobility, reliability and network accessibility. This framework has been used for the two cities of Tehran and Mashhad and using different eva‎luation indicators defined for each of the performance criteria at different hours of the day. The travel time data on Neshan (Iranian traffic online platform) have been collected in a 14-day period and in 30-minute cycle from 6:00 am to 10:00 pm for selected sections on highway and arterial functional levels of first and second grade, as well as the route between the origins and destinations of Municipal zones of Tehran and Mashhad. After the introduction and review of various eva‎luation indices under each of the desired performance criteria, the indices have been selected and calculated according to the criteria of index selection as well as usability according to the type of data collected. The results obtained for each of the indicators have been reviewed for both cities, and finally, by using the AHP (Analytic hierarchy process) method and determining the relative importance of the indicators to each other, a general comparison between the traffic performance status of the two cities has been made. The results show that Tehran city is better than Mashhad in terms of travel time index (mobility). Also, the results obtained from the calculation of the buffer index (reliability) show the better condition of the Mashhad city network compared to Tehran in terms of the uniformity of the travel time in different hours. The origin-destination travel time index (accessibility) also shows better results for Mashhad, although the values are close. Finally, the eva‎luation of two networks from the point of view of different criteria and according to the value of the criteria compared to each other, shows the relative superiority of the traffic performance of the transport network of Mashhad city. شاخص هاي ارزيابي، ، ، ، ،
