Drop lanes are not. Portland Bicycle Master Plan During the update of the Bicycle Master Plan, the City is considering to increase the standard bike lane width to 6.5 ft. Pedestrian and For shared bicycle and vehicle lanes (lanes >4.1m), the gutter flow spread width should be limited to 1.5m. The design rainfall intensity to use for these on-road cyclist checks is the lesser of the one year ARI, five minute duration, or 50 mm/hr. On-street parking. Gutter flow spread width should be restricted to 2.0m for the two year ARI. After seeing the success, Caltrans decided to re-stripe 50,000-plus lane miles of state highway system in the next decade with the new road demarcation lines replacing the longtime standard 4-in.-wide stripes. The 6-in.-wide striping consists of tape or thermal plastic embedded with glass beads.

For private motor vehicles in particular, narrower lane width, down to 10 feet or narrower in special cases, is correlated with all-user safety benefits.

Lane Widths Consideration should be given to increasing lane widths to 12 ft [3.6 m] in conjunction with rehabilitation projects where the highway is a high volume route utilized extensively by large trucks. For lane widths, AASHTO suggests that “local” roads be between 9 and 12 feet wide, that “collectors” be between 10 and 12 feet wide, and that “arterials” be between 10 and 12 feet wide (between 11 and 12 feet in rural areas). A width of 12 feet for through lanes is desirable on both rural and urban roadways, although the use of 9 foot to 11 foot wide lanes is not uncommon on low-volume roads (i.e., less than 400 AADT) Although 12 ft.
