Wow, there is a whole bunch of great stuff out there these days for pedestrian advocates.
Model Design Manual for Living Streets
Courtesy of the County of LA, this new manual has been generating a lot of buzz in the Complete Streets world. More info from the authors:
"The Model Street Design Manual was created during a 2-day writing charrette, which brought together national experts in living streets concepts. This effort was funded by the Department of Health and Human Services through the Los Angeles County Department of Public Health and the UCLA Luskin Center for Innovation. This manual focuses on all users and all modes, seeking to achieve balanced street design that accommodates cars while ensuring that pedestrians, cyclists and transit users can travel safely and comfortably. This manual also incorporates features to make streets lively, beautiful, economically vibrant as well as environmentally sustainable."

American Council of the Blind Pedestrian Safety Handbook
The third edition of the Council's Pedestrian Safety Handbook, the new online version of the handbook is envisioned as a "living document" that can be updated on an ongoing basis to address evolving vehicle technology and roadway design feathers.

Pedestrian Countermeasure Policy Best Practice Report

A discussion of relevant policies related to medians, refuge islands, walkways and shoulders from several states throughout the US.
State Best Practice Policy for Shoulders and Walkways
A brief summary of three state departments of transportation (New York State Department of Transportation, Pennsylvania Department of Transportation and the Oregon Department of Transportation) that have implemented policies and plans that promote the inclusion of paved shoulders and walkways.
State Best Practice Policy for Medians
A short description of three agencies that have implemented policies and plans that promote the inclusion of raised medians: the New York State Department of Transportation, the Oregon Department of Transportation, and the Florida Department of Transportation.
Safe Routes to School: Helping Communities Save Lives and Dollars
A comprehensive discussion of the SRTS program, along with specific data covering a variety of areas (e.g. traffic congestion, busing costs, physical activity) to help advocates make the case for SRTS.

Street Network Types and Road Safety: A Study of 24 California Cities
This study uses data from over 130,000 crashes in 24 cities to evaluate whether or not street network types affect roadway safety. The results show a correlation between roadway safety and both street network density and connectivity, with the highest risk of fatal or severe crashes occurring with very low street network density, and safety outcomes improving as intersection density increases.

Predicting Walkability
This research provides new methodologies for predicting the quality of the walking environment from the perspective of the user using operational and physical variables. The formulas were derived by combining the perception data gathered from participants in the community street reviews with measurements of the walking environment.

The Street Level Built Environment and Physical Activity and Walking: Results of a Predictive Validity Study for the Irvine Minnesota Inventory
The Irvine Minnesota Inventory (IMI) was designed to measure environmental features that may be associated with physical activity and particularly walking. This study assesses how well the IMI predicts physical activity and walking behavior and develops shortened, validated audit tools.

The authors find that while this inventory provides reliable measurement of urban design features, only some of these features present associations with increased or decreased walking. Characteristics of the sidewalk infrastructure, street crossings and traffic speeds, and land use are more strongly associated with walking for travel, while factors that measure aesthetics are typically less strongly associated with walking for travel.

Crossing Solutions at Roundabouts and Channelized Turn Lanes for Pedestrians with Disabilities
This report explores concerns over the accessibility of two complex intersection forms for pedestrians who are blind: intersections with channelized right turn lanes and modern roundabouts with one-lane and two-lane approaches. Based on the findings of this research project, significant impediments to the accessibility of these sites exist for pedestrians who are blind, but some crossing solutions can increase the accessibility in terms of improving safety and reducing delay.
Assessing the perceived safety risk from quiet electric and hybrid vehicles to vision-impaired pedestrians
This study investigates the accident risk posed by electric and hybrid vehicles and compares it with that for equivalent vehicles with traditional internal combustion engines to determine whether electric/hybrid vehicles are audibly more difficult to detect. This report presents the findings from the study, based upon a review of accident statistics, a programme of practical measurements to compare the noise of electric/hybrid and internal combustion engine vehicles, and a small-scale subjective assessment of the noise from these vehicles involving visually impaired participants.

Reducing Pedestrian Delay at Traffic Signals
This research, which was carried out between 2007 and 2010 in Auckland, Wellington and Christchurch, used techniques such as pedestrian attitude surveys, micro-simulation modelling and a literature review of international best practice to identify methods of reducing pedestrian delay at signalized intersections in these cities.

Distracted Driving: What Research Shows and What States Can Do

This report reviews and summarizes distracted driving research available as of January 2011 to inform states and other organizations as they consider distracted driving countermeasures. It concentrates on distractions produced by cell phones, text messaging, and other electronic devices brought into the vehicle. It also considers other distractions that drivers choose to engage in, such as eating and drinking, personal grooming, reading, and talking to passengers.

Effect of 20 mph traffic speed zones on road injuries in London, 1986-2006: controlled interrupted time series analysis
This report quantifies the effect of the introduction of 20 mph traffic speed zones on road collisions, injuries, and fatalities in London based on analysis of geographically coded police data on road casualties between 1986-2006.
