This document describes a proposed traffic jam locator system for Bangladesh. The key points are: 1. The system would use a mobile app, cloud server, and map tiles to provide traffic and navigation information to users. It would collect data from GPS, reports, and historical records to predict traffic conditions. 2. The system aims to minimize traffic issues through weather and road condition analysis, accident reporting, and optimized routing. This could lessen wasted time and fuel while improving travel. 3. Implementing this system could provide location-based ads, fleet tracking services, and value-added services to mobile users. Collaboration with Robi mobile could help develop and deploy the system at low cost using crowd-sourced data
