The desirable goal in passenger transportation is moving more people in fewer vehicles. This goal, in respect of road transport, can be attained by encouraging public transport modes like buses by assigning priority. This paper is concerned with application of micro simulation technique to study the impact of provision of reserved bus lanes on the flow of highly heterogeneous traffic on urban r...

1 This study evaluates the safety effects of automated mobile enforcement on urban arterial roads. 2 The before-and-after Empirical Bayes (EB) method was used to account for the regression-to3 the-mean effects and other confounding factors. Locally developed safety performance functions 4 and yearly calibration factors for different collision severities were obtained by using a reference 5 grou...

Arterials across the United States are experiencing far too many collisions. Agencies tasked with improving these arterials have few available effective solutions. Superstreets, called restricted crossing u-turns by the Federal Highway Administration (FHWA), are part of a menu of unconventional arterial intersection designs that may provide a promising solution. Up to this point, there is littl...

While vehicular flows on freeways are often treated as uninterrupted flows, flows on arterials are conceivably much more complicated since vehicles traveling on arterials are not only subject to queuing delay but also to signal delay. Prediction of travel time is potentially more challenging for arterials than for freeways. This paper proposes a simple approach for arterial travel time predicti...

Focusing on urban–rural development issues, this paper analyzes the necessity of coordinated development between the narrowing gap and integral development. An overall urban–rural development dynamic model aimed at two major objectives is pointed out. A principal component analysis (PCA)—Grey Entropy measurement model is proposed to evaluate urban–rural coordination from economic development, s...

Introduction: A composite index (or simply an index) is constructed with an objective to obtain a synoptic or comprehensive single number, representing a vast array of measurements on the multiple aspects of a ‘conceptual entity’ such as general price level, cost of living, level of economic development and regional disparities (Adelman and Morris, 1967; Pal, 1975; Mishra and Chopra, 1978; Mish...

Traffic conditions on arterials tend to be consistent during peak hours; yet, non-recurring events unpredictably affect these conditions. It is vital, however, for transportation planners as well as users of the facility to be able to assess traffic conditions. Therefore, a reliability performance measure is essential for evaluation. Reliability can take many measures. Various measures are chos...

this study investigates the status of heavy metals contaminations in urban soils of ostrava inthe czech republic. the main aim of this study was determination of concentration of cd, pb, zn, cu, mn,v and hg, assessment of contamination levels of metals in urban soils and verification of potential source ofmetals contamination. soil samples were collected from soil layer of 20 cm and metals were...
