A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas.
Highway 401 in Ontario, Canada, has an AADT of over 450,000 in some sections of Toronto. [3] One of the most important uses of AADT is for determining funding for the maintenance and improvement of highways. In the United States, the amount of federal funding a state will receive is related to the total traffic measured across its highway network.
A divided highway (U.S. Route 52) in the state of Indiana Savery Avenue in Carver, Massachusetts was the first divided highway in the U.S. [12] In the United States, this type of road may be called a divided highway, boulevard, parkway, expressway, freeway, or interstate, and has a grassy median or Jersey barrier separating the traffic directions.
The ICU method uses the Level of Service concept, in which reports on the amount of reserved capacity or capacity deficit. In order to calculate the Level of Service for the ICU method, the ICU for an intersection must be computed first. [3] ICU can be computed by: ICU = sum(max (tMin, v/si) * CL + tLi) / CL = Intersection Capacity Utilization
The median-side travel lane of the old two-way corridor becomes a passing lane. Other techniques involve building a new carriageway on the side of a divided highway that has a lot of private access on one side and sometimes has long driveways on the other side since an easement for widening comes into place, especially in rural areas.
The use of the K30 standard is mandated for the Highway Performance Monitoring System's comparisons of congestion. The K Factor also helps calculate the peak-to-daily ratio of traffic. K30 helps maintain a healthy volume to capacity ratio. [3] K50 and K100 will sometimes be seen.
The Alexander brothers were charged with conspiring to "repeatedly and violently drug, sexually assault, and rape dozens of victims."
The GEH formula is useful in situations such as the following: [4] [5] [6] Comparing a set of traffic volumes from manual traffic counts with a set of volumes done at the same locations using automation (e.g. a pneumatic tube traffic counter is used to check the total entering volumes at an intersection to affirm the work done by technicians doing a manual count of the turn volumes).
