Effect of Fog on Traffic Parameters in Mixed Traffic Condition

Pandit, Angshuman / Budhkar, Anuj Kishor

One of the adverse weathers affecting traffic movement is reduced visibility in the form of fog, which compromises traffic operations as well as safety. Research on fog effects over traffic parameters is mostly simulation-based, and a robust conclusion about fog effects is not arrived at. Furthermore, there is no study on effect of fog on mixed traffic conditions observed in developing economies. This paper compares macroscopic (speed and flow) and microscopic (headway) traffic parameters between foggy and non-foggy conditions in an inter-urban highway in mixed traffic conditions. Flow, speed and headways were obtained from the collected videos of traffic in foggy and non-foggy conditions and compared. Headway values for various car interactions are fitted in distribution functions. The findings of this paper estimate a lower speed value at capacity conditions for traffic in foggy weather. Further, there is a compromise in safety as overall headways are observed to be unsafe. Cars tend to follow leading car in case of fog but overtake truck and LCV more compared to non-foggy section. Truck-car headways are less in foggy weather. The results of this study can be used in various traffic applications like capacity estimation and safety analysis for foggy weather.
