Can you stick to the posted speed limit? The Washington State Legislature doesn't think so and fatal car crash statistics back them up which could result in speed cameras on the state's highways. Get our free m
Since the repeal of the 55 mph national maximum speed limit on US interstate highways, speed limits have been raised across the country to as high as 75 mph and more. While many studies have addressed the effects of increased speeds on accident frequency and severity, the factors that ...
The speed-limit/safety issue has been a matter of considerable concern in Indiana since the state raised its speed limits on rural interstates and selected multilane highways on July 1, 2005. In this paper, the influence of the posted speed limit on the severity of vehicle accidents is ...
Therefore, setting a speed limit that meets all these constraints at an acceptable level represents a challenging effort to decision-makers. In highways, posted speed limits may depend on several variables and, most importantly, on expert judgment. In the United States, the 85th percentile ...
The best-fit scatter plot for each travel time measure and posted speed limit category was selected based on the R2 value. 4. Results Fig. 2 shows the inter-relationships between the selected travel time measures and the estimated speed from the regional network model (x-axis) for all the ...

In order to reduce fuel consumption as a response to the Mid-East Oil Embargo in 1973, the federal government in the United States passed the National Maximum Speed Limit (NMSL) Law in 1974, which restricted the maximum permissible vehicle speed limit to 55 mph on all interstates roads. Thi...
and the connected vehicle environment (Ali et al., 2022,Ali et al., 2020a,Ali et al., 2019a). As our study focuses on, the hazard-based duration models are also applied to traffic control, such as modeling speed reduction behaviour on variable speed limit-controlled highways (Ali et al...
This paper studies the impact of speed limits on local air pollution using a series of date-specific speed limit reductions in Oslo over the 2004–2011 period. We find that lowering the speed limit from 80 to 60 km/h reduces travel speed by 5.8 km/h. However, we find no evidence of ...
