    This paper presents the technique using geometric road network (GRN) to improve data fusion method for vehicle trajectory analysis and reconstruction. The experiment used two methods of data fusion which are Linear-interpolation-based one and Kalman-filter-based one and used the simulation of detection and localization of vehicle moving in straight, big zigzag, small zigzag and arbitrary trajectories, with localization errors and multi-level loss of data. By comparing the data fusion methods with GRN and the ones without GRN, the result shows that the data fusion methods with GRN can reduce localization errors better than the ones without GRN in all level of data loss and all type of trajectories. In conclusion, using GRN can improve the efficiency of vehicle trajectory analysis and reconstruction.

    Crime incidents tend to increase steadily. To effectively respond to the incidents, police officers need to have a highly efficient incident reporting system. However, the telephone-based incident reporting system currently used has some limitations. It cannot cope with current problems and meet all requirements. Since mobile devices, especially smartphones, are prevalent, widely used and can transmit various types of information, they thus become an additional channel to the telephone-based incident reporting system. This paper proposes Mobile Crime Incident Reporting System, which comprises two parts. The incident report part was developed as a mobile application. To make it suitable for reporting crime or emergency incidents, UX dimensions guideline was used in the following order; 1) Identification 2) Emotion 3) Stimulation 4) Social relatedness/Co-experience 5) Visual and aesthetic experience and 6) Meaning and Value. The incident response part was developed as a web application. The system was tested by two groups of police officers; one acted as incident reporters, the other as incident response officers. The test result showed that the officers were satisfied with the application's user interface. They could easily learn how to use the system. The system also helped reduce the officers' response time because the system provided enough information which the officers needed to make quick and appropriate decision.
