Maryland SHA bike design guidelines
MD -- SHA Bicycle Design Guidelines 2012.pdf
This may be of interest only to infrastructure geeks, but SHA has a new comprehensive report on designs for bike infrastructure on or alongside state roads. It's a pretty big PDF, with a lot of design graphics.
Here are some of the intro clips:
It is SHA’s goal to provide these
accommodations as part of all roadway projects where it is appropriate and feasible to do so.
Creating a regional bicycle network that connects both on-road and off-road facilities to transit
stops, key community destinations, and other bicycle traffic generators and destinations is critical
to moving Maryland towards a complete multi-modal transportation system. As SHA develops this
system, it is imperative that we make our facilities as safe and efficient as possible for all roadway
users. To this end, recognizing the potential safety concerns of mixing bicycles with motor vehicle
traffic, SHA endorses the creation of a statewide bikeway network to increase motorist awareness
and acceptance of bicyclists as legitimate roadway users and to actively promote safe bicycling
along our highways.
All proposed activities which disturb the paved roadway area, disturb the adjacent curbline, or
adjust the line striping shall be reviewed for bicycle accommodations. These proposed activities
include, but are not limited to, replacing and/or modifying lane widths or shoulder widths. Every
effort shall be made to narrow the travel lanes in order to widen the shoulder to improve bicycle
compatibility. Prior to construction, the Assistant District Engineer (ADE) for Traffic will approve
the activities and verify that bicycle accommodations have been met as outlined in this policy.
It is SHA’s intent to provide bicycle accommodations on all roadways under its jurisdiction where
bicycles are allowed. However, if it is determined that full bicycle accommodations cannot be
provided, a design waiver shall be requested. A project can only proceed to advertisement or
construction (construction includes maintenance activities), if the project provides either full
bicycle accommodations or has been granted a design waiver. Noblanketdesignwaiverswillbe
granted on a projectwide or programwide basis. To avoid schedule disruptions late in a
project’s development, waivers should be submitted along with the conceptual scope approval
(Design Approval Memorandum or equivalent process). If during construction, it is found that a
project element cannot be constructed to meet full bicycle accommodations, a design waiver shall
be obtained prior to commencing work.
A design waiver may be considered for such things as impacts to right of way, utilities, structures
(such as bridges and drainage structures), environmentally or historically sensitive areas, or due to
excessive cost. Cost shall not be the sole consideration unless the inclusion of bicycle
accommodations increases the project budget (ROW, utilities, and construction) and cause adverse
impacts to the overall project funding. A waiver shall not be requested until all reasonable
alternatives to providing full bicycle accommodations have been exhausted and documented. The
significance of additional impact created by these alternatives over and above the basic project will
be considered in the waiver decision. The documentation of these alternatives will be required to
support the design waiver request.
Design waivers are not intended to exclude the implementation of bicycle facilities as part of a
project. Even with the design waiver, a project shall still be designed as close as practical to provide
full bicycle accommodations.
This is the type of provision that made Florida's similar guidelines almost useless. On every project bicycle facilities would be deemed infeasible. It's all in the application though.
