This paper predicts and compares the carbon monoxide (CO) concentration levels along Sembulan Road for years 2004 and 2014 using CAL3QHC air dispersion model at two major locations, i.e., at Sembulan Roundabout and Sutera Harbour Intersection, Kota Kinabalu, Sabah, Malaysia. The CO concentration “hot-spots” were also identified at Sutera Harbour Intersection, and the highest maximum 1-hr averag...

Finding a least-cost-path in a raster data format is a useful function in geographical information systems. However, existing algorithms are often inadequate for practical roadway planning. This paper improves conventional algorithms by including the considerations of spatial distances, anisotropic costs and the presence of bridges and tunnels in the paths. This new algorithm is implemented in ...

Road surfaces are exposed to solar radiation that generates thermal gradients and heat flow in the pavement layers. The stored can be harvested providing an untapped source of renewable energy. This paper presents design, construction, assessment improved thermoelectric energy system prototype for harvesting from roadway pavements. To accomplish this, various designs were simulated using Finite...

The first part of paper describes step by step installation of Switched Reluctance Motor & its drive. A special procedure for installation (Mechanical as well as Electrical) is developed in order to reduce acoustic noise, EMI interference and torque ripple of a motor. A serious electrical interference problem is solved using special designed screened cable. The second part of paper describes dy...

Abstract: A stochastic-computational scheme is presented for generating as-is graph structure spanning complex local geographics. In this schematics, GPS tracks uploaded by a multitude of probe vehicles are exploited to expand a network of feasible roadway patterns. By associating the GPS tracks with a multitude of Brownian motions conditioned by landmark allocation, the graph structure is succ...

In recent years, there has been an abundance of research that has used Poisson models and its variants (negative binomial and zero-inflated models) to improve our understanding of the factors that affect accident frequencies on roadway segments. This study explores the application of an alternate method, tobit regression, by viewing vehicle accident rates directly (instead of frequencies) as a ...

Studies have documented a link between distracted driving and diminished safety; however, an association between distracted driving and traffic congestion has not been investigated in depth. The present study examined the behavior of teens and young adults operating a driving simulator while engaged in various distractions (i.e., cell phone, texting, and undistracted) and driving conditions (i....

When reconstructing vehicle accidents, it is often important to record the accident scene roadway geometry. Survey techniques such as the plane surveying method and the coordinate and triangulation method, have been the most widely used recording methods and are generally accepted in the industry. This paper proposes to introduce video tracking photogrammetry as a new tool in gathering accident...

The run-off road crash (RORC) is a representative type of lethal crash. severity RORC has increased owing to combination factors, such as roadside geometry, traffic conditions, and weather/climatic conditions. In this study, model for estimating the was developed based on various including fixed objects, roadway environment. To develop model, accident data crashes with objects highways, well in...
