Highway Design Handbook for Older Drivers and Pedestrians. FOREWORD. The proportion of the population over age 65 is growing significantly. Older road users can be expected to have problems driving and as pedestrians, given the known changes in their perceptual, cognitive, and psychomotor performances, presenting many challenges to transportation engineers, who must ensure system . 01 (DE Revision) The “Standard Highway Signs and Markings” book (see Section 1A) and Delaware Standard Signs book prescribe design details for up to five different sizes depending on the type of traffic facility, including bikeways. Smaller sizes are designed to .
A driver comprehension analysis conducted in a laboratory setting with drivers 3060 years of age and older showed that green displays (those with the green ball alone, green arrow alone, or combinations of green ball and green arrow on the left-turn signal) were correctly interpreted with widely varying frequency, depending on the signals.

Vehicle/Pedestrian Deviations (V/PD). Operational Errors involve air traffic control (ATC) and Pilot Deviations typically involve an airman's mistake. A V/PD. occurs when a vehicle or pedestrian has entered the runway safety area without authorization from air traffic control. Annually, V/PD's comprise approximately 20% of total runway incursions. The pedestrian environment can be enhanced with more human-scale streets with narrower roadway widths, lower traffic speeds, smaller corner radii, planter strips, crosswalks (particularly crosswalks with signals, curb bulges, textured surfaces, raised surfaces, and adequate lighting), street trees, and pedestrian amenities.

Visibility and comprehension of pedestrian traffic signals. [Sara Pennak; Douglas J Mace; Mark Finkle; Turner-Fairbank Highway Research Center.; Last Resource, Inc.]. Portland Orange is the color of light emitted by the dont walk phase of pedestrian crossing signals in the United States and Canada.
The color was chosen to avoid confusion with regular traffic lights in conditions of poor visibility. Its chromaticity is specified by the Institute of Transportation Engineers in that body's technical standards, along with lunar white for the walk : CIECD.

Below is the uncorrected machine-read text. Additionally, a review of the literature, including published evaluation reports and blog posts that relate to bicycle signals with a focus on comprehension and visibility of signal-type traffic control devices, is.
Purpose: The purpose of this memorandum is to issue an Interim Approval for the optional use of bicycle signal faces. Interim Approval allows interim use, pending official rulemaking, of a new traffic control device, a revision to the application or manner of use of an existing traffic control device, or a provision not specifically described in the Manual on Uniform Traffic Control Devices.

The need for adequate sight distance at an intersection is best illustrated by a quote from the Green Book: "The driver of a vehicle approaching an intersection should have an unobstructed view of the entire intersection, including any traffic-control devices, and sufficient lengths along the intersecting highway to permit the driver to.

Uniformity of Application The uniform application of traffic control devices on a nationwide or statewide level reinforces driver expectancy and conditions them for what lies down the road.
Simplicity of sign messages and consistency of signing, signals and marking schemes reduces comprehension times of motorists.
This book will provide guidance in how to identify these elements in your collision investigations. The authors introduce you to the ways in which designers of vehicles and roadways historically often did not take into account the full range of road user characteristics.
The book discusses the substantial improvements in design principles and. A pedestrian phase is defined as a traffic phase allocated to pedestrian traffic that may provide a pedestrian indication either concurrent with one or more vehicular phases, or separate from all vehicular phases.
A traffic phase is defined as the green, change, and clearance intervals in a cycle assigned to specified movement(s) of traffic. Many traffic safety experts have contributed to this book in order to give you a comprehensive introduction to human factors as it pertains to driver and pedestrian behavior and traffic safety.
This new edition has been extensively revised, and contains new chapters on driver educationand driver : $ To quantify the effect of visibility aids versus no visibility aids, and of different visibility aids on the occurrence of pedestrian and cyclist-motor vehicle collisions and injuries.
Provides an introduction to temporary traffic control in work zones for individuals who work in the field installing and removing traffic control devices. This course covers the proper traffic control devices and applications for work zones that impact pedestrian traffic.
