The recent advances in computer visualization methods have made it possible to exploit the possibility of applying scientific visualization methods in critical research areas in the field of transportation engineering. In this paper we develop new visualization methods for road design and safety. Typically, roads are designed by combining horizontal and vertical roadway alignments, to allow for...

Theoretical methods are usually performed for ideal conditions to determine the illuminance and luminance but other design limitations should be considered in the real world. Also the visibility level is calculated by using background and target luminance under ideal conditions. In reality, there are many factors, which are very difficult to predict and include in lighting design equation. Huma...

In this paper, we describe a preliminary analysis of driver data collected during a recently completed small scale data collection effort. We will demonstrate that a popular method for computing Time To Lane Crossing (TLC) does not always accurately predict the driver's actual TLC. We will then use a memory based learning approach to show why this is. Finally, we will present results in predict...

the highway safety manual [hsm, 2010] recommends safety evaluations be performed beforeimplementing any roadway treatment to predict the expected safety consequences. safety consequences canbe measured using crash prediction models, crash modification factor (cmfs), or both. this paperdevelops a cmf to show the expected impact of red-light cameras (rlcs) on safety at signalizedintersections. a ...

In the mining process of an underground coal mine, dynamic load often causes great damage to roadway and affects normal mine. this paper, deformation surrounding rocks under static different disturbance intensities is studied by numerical simulation. The results show that same condition, greater strength is, more obvious roof displacement subsidence is. With increase in propagation distance, am...

In view of the complex asymmetric deformation characteristics inclined coal seam roadways and tensed shear failure anchor cable supports, support scheme an with a C-shaped tube is proposed. order to study its supporting effect on roadway, this paper first explores difference in performance between through double tests. Then, based roadway Pangpangta Mine, numerical simulation used roadway. The ...
