Transport engineering has become an increasingly important discipline in the engineering domain. Traffic flow theory is the foundation of most transport engineering studies. Moreover, the analysis of traffic flow is also the core of transport system analysis. The traditional traffic flow data used in modelling and validating traffic flow models are mainly loop detector data (fixed locations) and floating vehicle data (fixed vehicles), which are at relatively low resolution. With the new advances of traffic data collection, Bluetooth data, social media data, smart phone data, GPS data, machine vision data, vehicle to vehicle/infrastructure communication, and other sensor-based data, collecting high-resolution vehicle trajectories on a large scale becomes realistic, which provides an unprecedented opportunity for researchers to scrutinize vehicle movements, pinpoint locations of conflicts and disturbances, and fully describe tempo-spatial evolution of traffic flow dynamics and measure its impact on road safety. In this regard, it is with a high need to explore the role that new advances in data collection and analytics can play in improving the performance of traffic flow models and traffic operations.

With the increasingly more available high-resolution traffic and transport data, traffic flow models and transport system analysis can be revolutionized and informed. This call is to summarize the recent progress and advances in this area of research, with an attempt to benefit not only research communities but also practitioners.
