Impacts of Snowy Weather Conditions on Expressway Traffic Flow Characteristics

Impacts of Snowy Weather Conditions on Expressway Traffic Flow Characteristics

Snowy weather will significantly degrade expressway operations, reduce service levels, and increase driving difficulty. Furthermore, the impact of snow varies in different types of roads, diverse cities, and snow densities due to different driving behavior. Traffic flow parameters are essential to decide what should be appropriate for weather-related traffic management and control strategies. T...

Impacts of Weather on Urban Freeway Traffic Flow Characteristics and Facility Capacity

Adverse weather degrades the capacities and operating speeds on roadways, resulting in congestion and productivity loss. Without a solid understanding of the mobility impacts of weather on traffic patterns, freeway operators do not have the estimates of speed and capacity reductions to predict and simulate the impacts of traffic management strategies. Nearly all traffic engineering guidance and...

Image Processing Traffic Flow Measuring System of Hokuriku Expressway

The section between Nadachi-Tanihama .Ni igata Prefecture and Asahi .Toyama Prefecture(59.9km) of the Hokur iku Expressway was opened on July the 20th in 1988. This means that all the line of the Hokuriku Expressway was opened. This area has 22 tunnels and we built ImageProcessing Traffic Flow Measuring System as the part of NEC ITV System. It consists of 11 image-processing equipents and 54 I ...

Impact of Weather on Urban Freeway Traffic Flow Characteristics and Facility Capacity

Traffic Video Surveillance in Different Weather Conditions

Various parameters are studied in video-stream traffic surveillance. Weather conditions are one of the most important parameters, influencing the quality of traffic surveillance in any microlocation, such as the town of Metković in this study. This paper examines the influence of weather conditions on traffic surveillance based on the collection of visual data. The quality of the system was tes...
