Unmanned aerial systems (UASs) and unmanned vehicles (UAVs) have become increasingly attractive for numerous surveying applications in civil engineering, agriculture, many other fields. The are capable of performing photogrammetric data acquisition with equipped digital cameras that allows converting images to highly precise, georeferenced three-dimensional models. However, more studies needed demonstrate practical UAS UAVs on construction sites. In this project, photogrammetry technology...
Although the population of younger drivers has decreased over recent decades, their crash rates have increased. Research associated higher with societal influences and youthful behavior. was conducted to identify specific driving maneuvers which unsuccessful undertaking results in types crashes involving drivers. Four were identified as most prominent for young drivers: intersection, rear end, passing, single vehicle. The analysis performed by examining Kentucky database 1994-1996 period...
This study aims to use operational characteristics help determine the size and design of intersections on basis a targeted level operation. approach will allow for preliminary evaluation broader range possible designs, by screening out those designs considered less desirable or inappropriate performance. also more objective comparison all alternatives because options target same service level. The critical lane analysis method was an appropriate developing such estimates intersections....
On May 13, 2008, a fire occurred at the Faculty of Architecture Building Delft University Technology (TUD) in Netherlands. The ultimately led to collapse major portion building. Data was collected on this event by an international team that included researchers from Netherlands and U.S. data collection effort followed preliminary structural analysis identify possible contributing causes collapse. This paper will provide overview event, description system building, results response fire....
A proposed functional classification system has been developed to address context and multimodal accommodation of the existing system. The is intended facilitate optimal geometric design solutions while accounting for context, user needs, functions. new communicates improved information designer so that balanced designs can be achieved through documented prioritization roadway users. identifies groups, which include drivers, pedestrians, bicyclists. Fundamental elements each mode are...
The need to balance safety and operational efficiency at intersections requires special attention for accommodating left turn movements. Signalized epitomise this because unnecessary protection of turns can significantly increase delay. Left however, increases there is a proper balancing between the conflicting goals operations. long time required collect crash data evaluate use existing warrants render them frequently ineffective preliminary design tool assist in phasing decisions needed....
Developing a procedure that yields up to the maximum margin of return for investment requires an approach takes into account specific safety issues and commensurate design elements each roadway. Kentucky’s highway agency has embarked upon initiative tagged “practical solutions” which sets its goal toward reducing costs throughout project development process extended operations maintenance all facilities. This operationally defines within context practical solutions guiding principles...
The goal of this project is to develop a structured and objective evaluation process compare alternative design concepts evaluate them based on operations, safety, access management, pedestrian/bicycle accommodations. This approach permits more comparison all alternatives, since options target the same operational service level. Intersection Design Alternative Tool (IDAT) developed through effort capable evaluating 13 different intersection alternatives it would be invaluable in designs that...
The efficient and safe movement of traffic at signalized intersections is the primary objective any signal-phasing signal-timing plan. Accommodation left turns more critical because higher need for balancing operations safety. this study was to develop models estimate safety effects use left-turn phasing schemes. were based on data from 200 in urban areas Kentucky. For each intersection, approaches with a lane isolated considered their opposing through approach examine left-turn–related...
In the United States, highway functional classification has played a central role in planning and designing roadway projects. Classifications have served as surrogate for design inputs (e.g., speed). However, lacks resolution needed to develop context-sensitive designs prioritizes motor vehicles over other modes of transportation. NCHRP Report 855 introduced an expanded context system that supports more integrative context-adapted designs. This was subsequently adopted 7th Edition Policy...
This report describes the benefits quantification performed for proposed access management plan Kentucky. study evaluates capacity, safety and economic impacts associated with programs. The Kentucky program will seek to standardize driveway traffic signal spacing on all state maintained roadways in state. Transportation Research Board (TRB) Access Impact Calculator developed as a part of NCHRP Report 420, was used evaluate potential sample roadways. results this analysis were then...
The existence of extreme events in data sets can distort the accuracy computed statistics. Some favor censoring outliers while others oppose measured values. Detection methods are available for use univariate case, but identifying multivariate limited. Past research has provided detection methods, they limited by number outliers, predictor variables, or levels significance. A method detecting that is valid as many five presented. Critical values significance sample sizes from 10 to 100...
