View AllTransportation agencies use a variety of methods to evaluate the condition of pavements and the characteristics of their use. Methods range from in-pavement sensors to ride quality characterizations that require specially instrumented probe vehicles. However, the extensive labor, specialized training... From 2009-2014, an average of 43% of fatal crashes involved impaired drivers with a high of 55% in 2013 and a low of 28% in 2009. Impairment in injury crashes averaged 12%, ranging from 10%-14% annually. Sharp increases in travel volumes, shifts in traffic mix, and large increases in crashes have transformed the travel environment in the 17-county oil region of Western North Dakota in recent years. The area experienced an economic boom due to energy industry expansion, and although rates of oil production... Occupant seat belt use in fatal and injury crashes is considerably lower than conventional use reported by NHTSA. From 2009 - 2014, North Dakota's average occupant use in fatal crashes was 26% and in injury crashes, 68%. The share of injury crashes involving speed remained relatively stable from 2009-2014. Fatal speed-related crashes had more variation over the same time but have trended downward since 2010. Novice drivers are a focus in traffic safety program efforts because of their relatively high crash risk. The National Safety Council Alive at 25 course has been used by several states to promote teen driver safety. In a sample of 6,640 class participants, drivers had fewer crashes, traffic-related citations... This report evaluates two new glass-fiber reinforced polymer concrete reinforcement systems, which have been designed to serve as a non-corrosive alternative to steel reinforcement in reinforced concrete bridge girders. Due to the nature of the reinforcement geometry, these systems react in a way to... As part of the National LTAP program, funded by the Federal Highway Administration and state departments of transportation, one goal of the Utah LTAP Center is to provide training for new and long-term local government employees to help keep them up-to-date with appropriate technologies and regulations... In the 19th century, steamboats plied the Red River between Fargo, Grand Forks and Winnipeg. By 1900, regular railroad service for freight and passengers connected the two nations on that route. Rail passenger service between the two countries continued until 1971. Surface passengers were carried by... The objective of this report is to provide a benchmark for elevator managers in assessing performance, and supply a source for recognizing trends in the characteristics of North Dakota elevators. This report and the statistics mailed to individual elevators are presented as a source of information for... |
