Speed limit on most of Connector to increase to 60 mph after current project
BOISE - To improve safety and traffic flow, the speed limit on four
miles of the Connector (I-184) will be
raised from 55 mph to 60 mph at the conclusion of the current resurfacing project in that area, the Idaho Transportation Department announced.
Idaho
State Police, local law enforcement agencies and area city leaders met
with the transportation department in early June to discuss the change.
The section in question is the segment of the Connector from the Flying Wye to River Street.
The Connector averages about 57,000 vehicles per day.
ITD traffic engineers set the limit at the speed at which 85 percent of the traffic is driving to determine a safe and reasonable speed for a given road section, in accordance with federal safety guidelines. According to research, setting a speed limit according to that 85th percentile produces the fewest crashes.
The posted limit is a maximum speed when there are no obstacles or distractions and the pavement is dry. With icy, snow-covered or slick roads, it is always prudent to travel slower than the allowed limit. The speed-limit guideline is safe and prudent for the conditions.
"Speed-limit signs cannot replace common sense," said ITD southwest Idaho Traffic Engineer Kevin Sablan. "They are intended to supplement - not substitute for - the driver's judgment."
Limits help determine a reasonable speed for a particular road under ideal weather conditions. Speed Limits are imposed to assist Idaho law enforcement, and enforcement of the limits by them is essential. Limits encourage better traffic flow by reducing the variances in speed from one vehicle to the next, enhancing free-flowing movement.
