1 Virtual Traffic Signs Controller - Characterization Presentation - Performed by: Shahar Wolf Ido Raz Project instructor: Mony Orbach Technion – Israel Institute of Technology Department of Electrical Engineering High Speed Digital Systems Lab

2 Overview One of the causes for traffic accidents is the driver’s alert of the road. In order to raise the driver’s attention to risky situations in the road there’s a need for a system that will alert the driver in the necessary cases.

3 Project Goals Design and Implement a controller for virtual traffic signs alert system, that will: Manage data from the Motorola GSM/GPS G18 card. Cross-analyze and integrate the GPS data and the traffic data from the GSM, according to known profiles. Send appropriate feedback to driver (if necessary).

4 Environment Texas Instruments TMS320F2812 ezDSP controller (150MHz). Motorola G18 GSM/GPS card. Development Enviornment: Code Composer Studio ANSI C/C++

5 Development Environment

6 Hardware Architecture DSP GSM GPS DB

7 Hardware Architecture (cont.) DSP Adaptor GSM GPS SCIA SCIB

8 Inputs From GPS module: Data: Coordinates (location) Velocity Direction of progress etc… Communication feedback: Satellite communication status (locked/unlocked) From GSM module: Data: Regional traffic data (signs, traffic info, etc…) Communication status with the GSM cellular network Contacting GSM network cells Reception level etc..

9 Outputs Driver’s alert feedback: Deviation from regional traffic profile (for example: exceeding max. speed, attention to risky situations, etc..) Motorola G18 card (communication management): GPS module: Seek Satellite, lock Satellite, etc.. GSM modules: Seek cellular cell, contact cell, cells handshake, make sign of life, etc..

10 Layers and Modules Description GSMGPS Physical Layer Interface/Drivers Application GSM Module: -Communication functions -Request/get traffic data GPS Module: -Communication functions -Get data: location, velocity -Search and manage Database -Analyze data according to known profiles -Send feedback to driver

11 Main Application Algorithm Processing cycle: 1. Receive vehicle status data (location, velocity, direction) 2. Calculate Activity Sector 4. Analyze potential risky situations 3. Draw relevant data for the Activity Sector 5. Send feedback to driver if necessary

12 Schedule – 1 st Semester Study the development environment – 3 weeks –Code Composer Studio –The TI Controller features –The Motorola G18 card interface Design the interface between the controller and the G18 card – 3 weeks –Work on the interface should start before the Mid of 1 st Semester - Build GPS/GSM drivers – 5 weeks Simulate a primal test-case – End of 1 st semester

13 Schedule – 2 nd Semester Receive Traffic Profiles Design the virtual traffic signs application Optimize the DB and the application Debug Simulate system functionality
