  1. Technion – Israel Institute Of Technology Electrical Engineering Department Project Characterization Virtual Traffic Signal Presented by: Ron Herman Ofir Shentzer Instructor: Mr. Moni Orbach

  2. Project’s Goals • Define and implement a warning system for a vehicle driver, that will play as a real time warning signal. • Design and Construct a traffic signal data base, which would hold relevant information. • Develop an algorithm for data updating, while acting under system constraints.

  3. System Inputs The System relies on input from two different sources: • GPS (Global Positioning System), which is installed within a 3G cellular Phone. • Remote data base, which will be connected as means of updating local system data base.

  4. System Input : 1. GPS The GPS provides three main variables: • Direction. • Location. • Velocity.

  5. System Input : 2. Remote DB The remote data base is accessed via cellular communication. The data base holds a complete set of traffic signals, special events and their locations. The desired information is send to the local machine on demand. (according to pre- designed algorithm)

  6. System Output The system invokes two types of alarms: • Warning signal according to predetermined use-cases. • Traffic condition reports relevant to current location.

  7. System Block Diagram Remote Data Base Local Machine GPS & GSM Card Interface Controller Local Data Base Processing Unit User Interface

  8. Database’s Implementation Remote DB will be implemented using Microsoft SQL-Server technology, for better performance and modularity. As a start, for testing use, the remote DB will be stored on one of the laboratory’s servers, and will be accessed via lab network comunication (modeling celluar network).

  9. Example Use case • Approaching a Stop sign : As the car enters the sign’s defined access space (defined in the DB). It’s (the car’s) speed is checked (speed taken from GPS card data). If the car exceeds the pre-defined speed limitation (shown in a graph on the next slide and implemented in the system’s processing module) a warning signal is passed to the driver. • A sample check is taken every pre-defined fixed time interval.

  10. Example Use case (cont.) Forbidden Area

  11. Time Schedule (cont.) • Week 1 (till Thursday 6/5/2004) - define database’s internal formation - learning database’s implementation method - define (along with parallel group) GSM card interface

  12. Time Schedule (cont.) • Week 2 (till Thursday 13/5/2004) - start of database implementation - start design of GPS card simulator

  13. Time Schedule (cont.) • Week 3-4 (till Thursday 27/5/2004) - continue work on database implementation - finish design and implementation of GPS card simulator

  14. Current Semester’s Goals • Implementing GPS card simulator. • Completing work on remote DB. • Gathering ideas for Local DB storing and processing algorithms.
