Arrival time prediction provided by most of navigation systems is affected by several factors, such as road condition, travel time, weather condition, car speed, etc. These predictions are mainly based on historical data. Systems that provide near-real-time road condition updates, e.g. Google Maps, depend on crowdsourcing GPS data from cars or mobile devices on the road. GPS data thus has a long journey to travel from their sources to the analytics engine on the cloud before a status update is sent back to the client. Between the time taken for GPS data to be broadcast, received and processed, significant changes in road conditions can take place and would still be unreported, leading to wrong decisions on the route to choose. Road condition, especially average speed of cars, monitoring is of a local and continuous nature. It needs to be accomplished near GPS stream data sources to reduce latency and increase the accuracy of reporting. Solutions based on geo-distributed road monitoring, using Fog-computing paradigm, provide lower latency and higher accuracy than centralized (cloud-based) approaches. Yet, they require a heavy investment and a large infrastructure, which might be a limit for its utility in some countries, e.g. Egypt. In this paper, we propose a more dynamic approach to continuously update average speed on the road. The computation is done locally on the client device, e.g. the traveling car or the mobile device of the traveler. We compare, through simulation, our proposed approach to the fog-computing-based traffic monitoring. Simulation results give an empirical evidence on the correctness of our results compared to fog-based speed calculation.
