Abstract Travel time prediction based on deep learning techniques has received much attention in recent years. It is of great importance to advanced traffic management systems but remains a challenging problem as historical data are available in some but not all areas. Our preliminary experiments on New York City road network demonstrated that GPS pings recorded by in-vehicle GPS devices providing speed, position and time, do not cover the whole road network, thus, travel time in some regions could not be predicted accurately. However, predicting accurate travel time in each and every region in a city is fundamental to intelligent transportation systems. To predict travel time of target areas where little historical traffic data are available, we propose a transfer learning framework that exploits historical data of some source areas which are data-Abundant regions. To accurately predict travel time in source areas, we propose a hybrid architecture that models the spatial and temporal closeness as well as the road network typology. Experimental results on New York City road network show that our proposed model can achieve competitive performance comparing to baseline methods and classic regression models. © 2020 IEEE.
