A Sensing Coverage Analysis of a Route Control Method for Vehicular Crowd Sen...Osamu Masutani
Simulated evaluation of crowd sensing with vehicles for a Smart City. Route cordination of sensing vehicles is a key to enhance sensing coverage of participatory crowd sensing system. We provide a simple methodology to realize suitable cordinated traffic control method by means of shortest cost finding with dedicated cost function aware of sensing demand in a city.

Toward a resilient prediction system for non-uniform traffic data Osamu Masutani
We developed a traffic prediction system which enhances a traffic information service. The prediction method is based on time series analysis and is applicable to short to long term prediction. Traffic information system are real-time and real-world system therefore it suffers various kind of disturbance from environment. To preserve traffic prediction quality, we need fundamental treatment on overall system so that the prediction engine be tolerant toward incomplete traffic data feed or non-stationary traffic data. A solution for incomplete data feed is a combination of data for multiple links. A solution for non-stationary traffic is a traffic simulation dedicated to traffic accidents. With these enhancements toward cyber disturbance and physical disturbance, the system resiliency can be higher.
An event detection method using floating car dataOsamu Masutani
This paper presents a method which detects events from floating car data (FCD). In traffic prediction, an event is one of unexpected factors which deteriorates the prediction performance. If occurrences of events are provided to prediction system beforehand, the prediction will be improved. Firstly, we confirmed contribution of event information to a traffic prediction accuracy. Then the paper will show that spatio-temporal pattern of zonal traffic attraction and generation is an intelligible trail of an event. Finally, the paper will propose an event detection and prediction method using PCA and HMM. The result shows feasibility of event prediction in high accuracy in certain condition.
