We develop a formula (Theorem 5.1) which allows to compute top Chern classes of vector bundles on the vanishing locus V (s) of a section of this bundle. This formula particularly applies in the case when V (s) is the union of locally complete intersections giving the individual contribution of each component and their mutual intersections. We conclude with applications to the enumeration of rat...

Aims: The aim of this study is to evaluate the queue length isolated signalized intersections, which used HCS2010 and SIDRA Intersection 8 traffic software. Background: One important parameters performance a management system length, especially in congested situations. For estimation back many analyzing models are based on Highway Capacity Manual (HCM2010). Objective: values obtained from these...

This study seeks to identify the optimal location of an advance point traffic detector (APTD) to support green termination algorithms for enhanced dilemma zone protection systems at high-speed isolated signalized rural intersections. This is done by developing a nonlinear optimization model with the objective to maximize the opportunities to predict empty dilemma zones during a look-ahead time ...

Red light cameras may have a demonstrable impact on reducing the frequency of red light running violations; however, their effect on the overall safety at intersections is still up for debate. This paper examined the safety impacts of Red Light Cameras (RLCs) on traffic crashes at signalized intersections using the Empirical Bayes (EB) method. Data were obtained from the Florida Department of T...

Introduction Perceived waiting time (PWT) at signalized intersections differs from the real value of waiting time (WT), and varies with signal design. The onerousness of delay depends on the conditions under which it is experienced. Using weighted travel time may contribute to optimal signal control if its use can improve upon assuming that all time is weighted equally by users. This research e...

Identification of sets of objects with shared features is a common operation in all disciplines. Analysis of intersections among multiple sets is fundamental for in-depth understanding of their complex relationships. However, so far no method has been developed to assess statistical significance of intersections among three or more sets. Moreover, the state-of-the-art approaches for visualizati...

Recent growth of the geo-spatial information on the web has made it possible to easily access various and high quality geo-spatial datasets, such as road networks and high resolution imagery. Although there exist efficient methods to locate road intersections from road networks for route planning, there are few research activities on detecting road intersections from orthoimagery. Detected road...

A new theoretical approach for the determination of capacities at All-Way Stop-Controlled intersections is presented. This approach is based on the Addition-Conflict-Flow method developed from the graph theory. The point of view related to the traffic streams in contrast to existing procedures, which handle only the approaches allows a systematic and realistic analysis of the traffic process at...
