"The most thoughtful and judicious one-volume history of the war and the American political leaders who presided over the difficult and painful decisions that shaped this history. The book will stand for the foreseeable future as the best study of the tragic mistakes that led to so much suffering."—Robert Dallek Many books have been written on the tragic decisions regarding Vietnam made by the young stars of the Kennedy and Johnson administrations. Yet despite millions of words of analysis and reflection, no historian has been able to explain why such decent, brilliant, and previously successful men stumbled so badly. That changes with Road to Disaster. Historian Brian VanDeMark draws upon decades of archival research, his own interviews with many of those involved, and a wealth of previously unheard recordings by Robert McNamara and Clark Clifford, who served as Defense Secretaries for Kennedy and Johnson. Yet beyond that, Road to Disaster is also the first history of the war to look at the cataclysmic decisions of those in the Kennedy and Johnson administrations through the prism of recent research in cognitive science, psychology, and organizational theory to explain why the "Best and the Brightest" became trapped in situations that suffocated creative thinking and willingness to dissent, why they found change so hard, and why they were so blind to their own errors. An epic history of America’s march to quagmire, Road to Disaster is a landmark in scholarship and a book of immense importance.

This book contains selected papers resulting from the 2020 International Conference on Road and Traffic Engineering (CRTE 2020) covering Road Engineering and Traffic Engineering, aiming to provide an academic and technical communication platform for scholars and engineers engaged in scientific research and engineering practice in the field of Road Engineering and Materials, Traffic Engineering and Management and Transportation Engineering. By sharing the research status of scientific research achievements and cutting-edge technologies, it helps scholars and engineers all over the world to comprehend the academic development trends and broaden research ideas. So as to strengthen international academic research, academic topics exchange and discussion, and promote the industrialization cooperation of academic achievements.

This thesis focuses on disaster management. More specifically, the simultaneous planning of the distribution of disaster relief goods and the clearance of blocked roads immediately after the occurrence of a natural disaster such as an earthquake, a flood or a hurricane is investigated.
