Fog leads to dangerous driving conditions. Along the highway of the coast of the Bohai gulf, the occurrence frequency is higher than other places in the Beijing area. Nowadays, numerical weather prediction is widely used in China. Based on numerical model (MM5), the statistical method is applied to build a forecast model for seven stations along the highway. When fog is forecast it is tracked by satellite images. Beijing Weather Information Service provides forecast products each day via various media. These products include two fog forecasts of the next 24 hr period for each site along the highway. Also, there are four real time observations and 48 images of geostationary meteorological satellite of fog products in the Huabei region, processed with the combination of multi-channel sensors in order to make up the shortage of the AWS (Automatic Weather Station). The warnings are issued to highway managers and to the general public if fog occurs. Keywords: fog forecast, satellite image, tracking fog, transportation service.
