A path shadowing number model for ITS pedestrian-to-vehicle communication in urban streets

Although it is effective in realistic path loss prediction to consider propagation path shadowing by the vehicles which run a roadway in development of the various ITS in a city area road, it is further required in development of pedestrian-to-vehicle communications that the path loss model which can take into consideration the influence of path shadowing due to pedestrians moving on a sidewalk. This paper presents a model for counting the number of propagation path shadowing due to pedestrians walking on a sidewalk. Proposed model is compared with the simulation results and it is found that predictions give the mean number of shadowing for all of multi-reflection paths in straight roads.
