Traffic Speed Estimation Based on Multi-source GPS Data and Mixture Model

The traffic speed information of an urban road network is generally estimated using the widely available taxi GPS data. However, taxi usages are preponderantly restricted to areas with high population density, which results in limited spatial …

Estimating Traffic Flow in Large Road Networks Based on Multi-Source Traffic Data

Traffic flow data collected by traffic sensing devices is crucially important for transportation planning and transportation management. However, traffic sensing devices are typically distributed sparsely in road networks owing to their high …
