Lights and barriers will be used on the northbound approach to the tunnels to control traffic volumes when the free-flow tolls are introduced in the autumn.
Future air traffic control will have to rely on more advanced automation in order to support controllers in their job of safely controlling increased traffic volumes.
Our modeling of the relationship between avgas and blood lead could be improved by incorporating wind direction information, by obtaining information about where piston-engine aircraft typically take off or land at each airport, and by controlling for air traffic volume.
Our results suggest that child pedestrian injuries at intersections are associated with intersection control type, traffic volume, and land use characteristics.
This adjustment was expected to provide a better control for traffic volume of the day, as the resulting RR of temperature could be interpreted as the increase in risk of crashes with driver performance associated factors for each 1°C increase in temperature on days that had the same number of vehicle crashes without driver performance associated factors.
The EB study controls for trend, traffic volume and regression to the mean, while the before and after study only controls for trend and traffic volumes.
cAverage Annual Daily Traffic (Total annual traffic volume/365) dModel mutually controls for Speed Limit, Traffic Volume, and Shoulder Width eModel mutually controls for Road Type, Surface Type and Road Width fFarm to market route gUnit: 5 feet.
We attempted to control for changes in traffic volume by including dummy variables for day of the week and for the strata combining year and month, which had been shown to produce estimates of associations between meteorological parameters and traffic accidents in the Netherlands that were consistent with estimates from models adjusted for traffic volume (Brijs et al. 2008).
The BB test compares the proportion of a particular collision configuration observed at one location with the proportion of the same collision configuration found at other reference locations which are similar to the target location in terms of selected traffic and roadway characteristics (e.g., traffic volume, traffic control, and number of lanes).
In this study, the RCA is substituted for Michigan traprock virgin aggregates (VA) in a light traffic volume HMA (control mix) at the rate of 25, 35, 50 and 75.
The aim of our research is to find a method to control the quantity of traffic pollutants emission through adjusting and controlling the composition of vehicle types, and then the traffic volume and vehicle's running speed indirectly.
