Pg 7-14: NCHRP Report 783: Evaluation of the 13 Controlling Criteria for Geometric Design

"In 1985, the FHWA designated 13 specific design elements as controlling criteria for roadway design (see Mitigation Strategies for Design Exceptions). The 13 controlling criteria are (1) design speed, (2) lane width, (3) shoulder width, (4) bridge width, (5) structural capacity, (6) horizontal alignment, (7) vertical alignment, (8) grade, (9) stopping sight distance, (10) cross slope, (11) superelevation, (12) vertical clearance, and (13) horizontal clearance.

Pg 531-543: Manual on Uniform Traffic Control Devices (MUTCD), 2nd edition

The Manual on Uniform Traffic Control Devices, or MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public travel. The MUTCD is published by the Federal Highway Administration (FHWA) under 23 Code of Federal Regulations (CFR), Part 655, Subpart F.

Pg 79-84: PedSafe Countermeasures San FransicoPhase 2 Final Report

This report presents the methods and key findings from San Francisco PedSafe, a comprehensive pedestrian safety planning and engineering project. It is one of three such projects in the nation funded by the Federal Highway Administration (FHWA) to evaluate:
In Phase I: The effectiveness of a pedestrian safety plan targeted to higher-injury areas;
In Phase II: The implementation of a range of mostly low-to-moderate-cost, innovative safety improvements.

Countemeasures_Traffic Management: Pedestrian Safety Guide and Countermeasure Selection System (PEDSAFE)

The Pedestrian Safety Guide and Countermeasure Selection System is intended to provide practitioners with the latest information available for improving the safety and mobility of those who walk. The online tools provide the user with a list of possible engineering, education, or enforcement treatments to improve pedestrian safety and/or mobility based on user input about a specific location.

Pg 41-43: Non-Motorized User Safety A Manual for Local Rural Road Owners

Many of the roads in the U.S. are non-Interstate, local and rural roads that are maintained and operated by local agencies, such as towns, counties, and Tribal governments. Non-motorized modes of travel, such as biking, walking, and riding horses or horse-drawn carriages can be expected along these roads and may face safety concerns when utilizing the same roadway as motorized travelers. This Non-Motorized User Safety Manual focuses on low-volume local rural roadways and rural villages and describes a process that can be used to address the safety of non-motorized users.
