US 14/WIS 11 (Janesville - US 14/I-43) - Need/purpose
The need for studying improvements to the US 14/WIS 11 corridor
is based on a combination of factors:
System linkage and route importance
There are inadequate system connections to disperse local
traffic congestion and provide alternate routes for highway
construction, local or regional emergencies, incident
management, and evacuation planning. Driver expectations of the
designation and use of the highways as a part of the national
highway system and a Corridors 2020 Connector route are not
being met. In addition, portions of US 14 and WIS 11 serve as
alternate routes in the event of a closure or incident which
causes significant delays on I-39/90.
Existing and future travel demand
Higher traffic volumes and accompanying slower speeds and
lengthening signal times lead to longer travel times in the
study area. Higher traffic volumes and slower speeds also
degrade the local air quality.
System safety is degrading and crash rates are increasing.
There is also inadequate access control through the study area,
which contributes to decreased safety. Several segments
currently have crash rates that exceed the statewide average.
Increased traffic volumes and congestion are decreasing
Level of Service (LOS) measures below operational standards. LOS
measures characterize the operating conditions of a roadway
based on several factors including actual speed versus posted
speed, travel time, and intersection delay. LOS grades
range from A (least congested) to F (most congested.)
Increases in population and development in the study area are
contributing to increased traffic volumes and congestion.
Multi-modal transportation can be enhanced, encouraging use of
alternative forms of transportation and providing opportunities
for those unable to operate motor vehicles on their own. The
public and local government have requested improvements to the
highway system in the study area.
