G . Channelization
Channelization is often used to prevent cutthrough traffic onto local streets or to control turning traffic in or out of a neighborhood . Channelization can also be used to reduce speed , create an opportunity for landscaping , control turning movement , direct / guide pedestrians , and to increase the safety of pedestrians and bicyclists . Channelization can be at streetlevel , provided there is a physical separation , or they can be elevated to create a separation from the roadway . The curb creates the separated space , as well as preventing passengers from opening doors into the cyclists ’ track and discouraging pedestrians from walking on the facility ( Figures 7.9.19 to 7.9.21 ).

Design Criteria :
• Provide regulatory signage , pavement markings , landscaping , bollards , or raised islands to direct vehicular , bicyclist , and pedestrian traffic .
• Confirm proper warrants and public interest needs during the development of channelization recommendations .
• Signalization , pavement markings , and signage to comply with City of Arlington , MUTCD , AASHTO , and ADA standards .
• The major street must be wide enough to accommodate a 10-foot median .
• Provide treatment only along busy bicycle and pedestrian routes .
