This document summarizes an integrated transport planning project in Hanoi, Vietnam called REMON. The project aims to reduce emissions and energy consumption from transport using real-time traffic monitoring data from floating car data and floating phone data. It involves partnerships between German and Vietnamese organizations to develop tools to evaluate short-term traffic optimizations and long-term transport, urban planning, and management improvements. The 3-year project studies Hanoi's growing traffic issues and tests using GPS data to monitor traffic and inform transport strategies.
