TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 356: Pavement Markings--Design and Typical Layout Details identifies variations in pavement marking designs, practices, and policies, as provided by 48 of 50 state departments of transportation, and transportation agencies from the District of Columbia, Puerto Rico and four cities.

ÒTen thousand years of history, and we find the remains of ancestors removed from their burial mound . . . Ò Impressions of the past, markings on earth, are part of the world of Karenne Wood. A member of the Monacan tribe of Virginia, she writes with insight and grace on topics that both reflect and extend her Native heritage. Markings on Earth is a cyclical work that explores the many dimensions of human experience, from our interaction with the environment to personal relationships. In these pages we relive the arrival of John Smith in America and visit the burial mounds of the Monacan people, experience the flight of the great blue heron and witness the dance of the spider. We also share the personal journey of one individual who seeks to overcome her sense of alienation from her people and her past. WoodÕs palette is not only Nature but human nature as well. She writes pointedly about shameful episodes of American history, such as the devastation of Appalachia by mining companies and the ÒdisappearanceÓ of Indian peoples. She also addresses forms of everyday violence known to many of us, such as alcoholism and sexual abuse. Wood conveys an acceptance of history and personal trauma, but she finds redemption in a return to tradition and a perception of the worldÕs natural grace. Through these elegantly crafted words, we come to know that Native writers need not be limited to categorical roles determined by their heritage. Markings on Earth displays a fidelity to human experience, evoking that experience through poems honed to perfection. It is an affirmation of survival, a work that suggests one personÕs life cannot be separated from the larger story of its community, its rootedness in history, and its timeless connections to the world.

"Perhaps the greatest testament of personal devotion published in this century." — The New York Times A powerful journal of poems and spiritual meditations recorded over several decades by a universally known and admired peacemaker. A dramatic account of spiritual struggle, Markings has inspired hundreds of thousands of readers since it was first published in 1964. Markings is distinctive, as W.H. Auden remarks in his foreword, as a record of "the attempt by a professional man of action to unite in one life the via activa and the via contemplativa." It reflects its author's efforts to live his creed, his belief that all men are equally the children of God and that faith and love require of him a life of selfless service to others. For Hammarskjöld, "the road to holiness necessarily passes through the world of action." Markings is not only a fascinating glimpse of the mind of a great man, but also a moving spiritual classic that has left its mark on generations of readers.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 759: Effective Removal of Pavement Markings aids in the selection of safe, cost-effective, and environmentally acceptable practices for the removal of work zone and permanent pavement markings. The practices highlighted in this report emphasize minimal damage to the underlying pavement or visible character of the surface course." -- Publisher's description

The report describes a laboratory test method to predict the initial retroreflectivity of pavement markings in the field based on the quality of the applied glass beads.
