I ~ .. streets. Highway 96 is designated as an "A-minor" arterial in the regional transportation system plan and therefore is intended to serve more of mobility function and less of an access function. II Accident data shows that the safest roadways are those that are on either end of the range and . provide primarily one function, either access or mobility. The highest accident rates are found on the arterial streets which serve both an access and mobility function. The frequency of access on an arterial roadway affects both safety and capacity. Accident data shows that accident rates on an . arterial street increase as the number of access points inCrease. Therefore. limiting access will help to reduce accidents on an arterial roadway. The accident data also shows that arterial streets with separate turn lanes have lower accident rates than arterial streets without turn lanes. Turn lanes also .. help to increase the capacity of the roadway by getting turning traffic out of the through lanes. Based on the above information and general guidelines established in other studies the desired access II spacing on Highway 96 is as follows: Minimum spacing between signalized intersections, Y:, Mile II Minimum spacing between full access intersections - 1/4 Mile II Minimum spacing between right,in and right-out access - 1/8 Mile -- It is acknowledged that this spacing is not feasible in many locations with the current land uses. On the other hand it is a standard which should be strived for wherever possible. In some areas it may be necessary to plan for a change in land.tises where the existing land uses (such as single family II residential) is inconsistent with the function of Highway 96. Single family residential is one of the least compatible land uses along an arterial such as Highway 96 because of the need for frequent access and because they are the most sensitive to the noise created by tra'ffi~ using the arterial. In II addition the frequent access needed by these land uses make it extremely difficult to mitigate the noise impacts of the arterial. - SIGNAL LOCATION CRITERIA - Traffic Signals are a commonly used traffic control device at the intersection of two more important roadways. However, traffic signals are not the best traffic control device at every location. If used incorrectly traffic signals can increase delay and accidents. Therefore traffic engineers have , developed warrants that help to identify where the use of traffic signals are appropriate. These traffic signal warrants are documented in the Manual on Uniform Traffic Control Devices. 111 Warrants for Traffic Si!!nal Installation The Minnesota Manual on Uniform Traffic Control Devices states; "Traffic control signals should III not be installed unless one or more of the signal warrants in this Manual are met. The satisfaction of a warrant or warrants is not in itself justification for a signal." ,- - There are II signal warrants identified in the Mirinesota Manual on Uniform Traffic Control , 36 '~~'..
