Traffic information provision suitable for TV broadcasting based on macroscopic fundamental diagram from floating car data

This paper describes the feasibility study on the traffic information provision which is suitable for TV broadcasting by using floating car data (FCD). Recent telematics services provide traffic information via on-board car navigation units or portable navigation devices which facilitate interactive use but for limited number of users. On the other hand, the information provision via TV broadcasting has large number of viewer and may seems have significant influence on their travel behaviors especially in the case of singular traffic conditions. However the way of expression of traffic information via broadcasting has limitation in the interaction and the sparse resolution on TV monitors. In this paper, we will propose the mesh-wised traffic indices in terms of the fluidity and the singularity in traffic conditions based on the macroscopic fundamental diagram (MFD) of traffic flows. After the discussion on the theoretical framework, the preliminary studies using taxi probe data in Tokyo will be presented.
