and follow-up headway values based on a comprehensive evaluation of roundabouts throughout the United States. The recommended operational models by NCHRP 3-65 will be incorporated into the next update of the Highway Capacity Manual (HCM). Although this NCHRP study contains a significant amount of data (including more than 500 h of video at various roundabout locations), the data do not include ...

Lane and Terry (2000) defined mood as “a set of feelings, ephemeral in nature, varying in intensity and duration, and usually involving more than one emotion” (p.16). They proposed a conceptual framework for predicting performance from mood states assessed by the Profile of Mood States (McNair, Lorr, & Droppleman, 1971) or its derivatives. The conceptual model indicated that depressed mood infl...

This dataset contains 154 images in an urban environment originally obtained from the KITTI dataset (see [1]). The images show well a demarcated (white lines) two lane highway road. The detection algorithm/method is requried to only consider the lane the recording platform was driving on (i.e the right lane). Apart from this other challenges include, shadows, variations in lane-markings and pre...

Figure 1. IFNGR1 RFLP detected by Southern blot analysis of Taql digested human DNA. The two alleles arc identified by 6. lkb (Al) and 3.2+2.9kb (A2) bands in a .8% agarosegel. Lane 1: Al homozygous; lane 2: A2 homozygous; lane 3: heterozygous. Hybridization and washing conditions were 50% formamide, 3x SSC, 37°C and .2x SSC, 60°C, respectively. figure l.VIL 2 RFLP detected by Southern Blot ana...

Pedestrian behavior and safety at roundabouts are not well understood, particularly for pedestrians with sensory or mobility impairments. A previous study in which participants indicated when they would cross suggested that blind pedestrians miss more crossing opportunities and make riskier judgments than sighted pedestrians. The present study replicated these findings and analyzed actual stree...

We extend previously defined particle filters for lane detection by using a more general lane model supporting the use of two independent particle filters for detecting left and right lane borders separately, by combining multiple particles, traditionally used for identifying a winning particle in one image row, into one superparticle, and by using local linear regression for adjusting detected...

Globally developing economies and opportunities cause an increase in the density of people city centers, thus extraordinary number motor vehicles. The vehicles complicates creation a sustainable traffic network. Waiting times stops psychological, physical environmental problems. efficiency intersections is vital to ensure transportation. Modern roundabouts outperform signalized roundabouts, the...

The detection of lane boundaries on suburban streets using images obtained from video constitutes a challenging task. This is mainly due to the difficulties associated with estimating the complex geometric structure of lane boundaries, the quality of lane markings as a result of wear, occlusions by traffic, and shadows caused by road-side trees and structures. Most of the existing techniques fo...
