Benjamin Heydecker’s research lies in developing mathematical and statistical analyses in transport studies. He has pursued this along three broad themes within the field of transport studies: 
o Transport safety, including the analysis and interpretation of road accident data, 
o Traffic management and control, including real-time information, management and control systems with a view to promoting cooperative usage of road and railway networks to benefit users and citizens, and 
o Transport planning methods, including dynamic transport modelling and discrete choice methods.

The interrelationships between these themes, and between each of them and methodologies for estimation, design and management, are of special interest to him. He is currently exploring opportunities presented by emerging information and communications technology to promote cooperation among users, between users and they transport system, and among components of the transport system.

He serves on the editorial boards of the Networks and Spatial Economics, Sustainable Transportation and Transportmetrica journals. He is a Fellow of the Institution of Mathematics and its Applications, Fellow of the Royal Statistical Society, Fellow of the Transport Research Foundation and Member of the Chartered Institution of Highways and Transportation.
