Pg 35-60: Application of Pedestrian Crossing Treatments for Streets and Highways

TRB's NCHRP Synthesis 498: Application of Pedestrian Crossing Treatments for Streets and Highways compiles information on the state of existing practices regarding application of pedestrian crossing improvements, and does not produce new guidance. The report includes a survey of state departments of transportation (DOTs) and local transportation agencies, a synthesis of current recommended practice and policy guidance, and a literature review of safety evidence for more than 25 pedestrian crossing treatments.

Pg 532-538: Traffic Control Devices Handbook

The Handbook augments the 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD). The Traffic Control Devices Handbook, 2nd Edition provides guidance and information to implement the provisions of the MUTCD. The objective of the Handbook is to bridge the gap between the MUTCD requirements and field applications. Additional guidance is provided on the new MUTCD requirements to clarify these MUTCD provisions. The Handbook does not establish policy, procedures, or standards for an agency, or set the "standard-of-care" for decisions on traffic control devices.

Volume 3;Chapter 15: Highway Safety Manual

2.8: A Policy on Geometric Design of Highways and Streets, 6th Edition

A Policy on Geometric Design of Highways and Streets, 6th Edition, 2011, commonly referred to as the “Green Book,” contains the current design research and practices for highway and street geometric design. The document provides guidance to highway engineers and designers who strive to make unique design solutions that meet the needs of highway users while maintaining the integrity of the environment. It is also intended as a comprehensive reference manual to assist in administrative, planning, and educational efforts pertaining to design formulation.

Pg 86-89: 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.
