ABSTRACT

PLASH (A Platform for Location Aware Service with Human Computation) is proposed as a platform to allow fast deployment of various location aware services. PLASH applies Web2.0 and human computation to consolidate the intelligence and efforts of general public that users are also participators and contributors. This difference with the traditional intelligent transportation system and location aware services makes the designs are obviously different.

PLASH consists of a multi-layered platform and application systems. The platform includes Communication Layer, Data Layer responsible and Service Layer. Each layer of the platform communicates via APIs to provide modularization and extensibility. In addition, PLASH allows application builders to develop and contribute their mature applications as a service accommodated in the Service Layer for other application builders to expand and create more sophisticated applications. To ease the tasks of develop and deploy applications, the platform provides an application development environment for application builders. In this application development environment, builders are able to use our Application Specification Language (ASL) and our Graphical User Interface (GUI) to mash-up, create, and share applications/services. Furthermore, PLASH application development environment simplifies not only application builders’ task and development circle but also intergradations of sub-project in the PLASH project.

We are working on the following projects to support the goals of PLASH. Those technologies are (1) Comfort Measuring System for Public Transportation System, (2) Location Trajectories Access, Storage and Application, (3) Travel Route Suggestion Based on Human Computation, (4) Location-Aware Community Common Experience Integration and Summarization System, (5) Data Sharing and Analysis on Taipei e-Bus and Taxi, (6) Trajectory Urban Traffic Mining, and (7) Traffic Modeling and City Travel Route Planning.
