This paper evaluates various options for addressing traffic problems on the Malahat highway corridor, north of Victoria, British Columbia. A combination of transit and vanpool service improvements, support strategies, and incremental roadway improvements is by far the most cost effective and beneficial option. Current planning tends to undervalue this approach by ignoring some costs of highway ...

C and delay are two major parameters for evaluating intersection operations. While models and procedures are available to estimate these parameters given some other easily obtainable traffic flow parameters, traffic engineers often have to conduct field measurements to verify the results given by available models and procedures. Capacity and delay models are provided by the 1994 update of the H...

In utilizing various alternative energy, generators are used to convert energy into electrical for example, biomass, wind, and hydroelectricity. Generally, the measurements made on rotational speed in form of revolutions per minute (RPM). developing lab-scale power sources, availability with complete quality specifications is still minimal, including RPM capacity. Therefore, measurement which c...

INTRODUCTION The performance of violence risk assessment instruments can be primarily investigated by analysing two psychometric properties: discrimination and calibration. Although many studies have examined the discrimination capacity of the Violence Risk Appraisal Guide (VRAG) and other actuarial risk assessment tools, few have evaluated how well calibrated these instruments are. The aim of ...

Users of the POND decision support system may often be interested in tailoring the models to one or more fish species at a given location. Manual calibration of the fish bioenergetics model in POND for Nile tilapia (Oreochromis niloticus) growth has previously been reported (Bolte et al., 1995). However, estimating suitable parameters for complex, non-linear simulation models by manual calibrat...

Vehicular platooning is one of the most challenging issues affecting level service (LOS) two-lane roads. This phenomenon has been involved with variables governing performance measures. Thus, to improve quality these roads and predict a comprehensive model for future plans under this phenomenon, present study aimed evaluate effect vehicular on measures then identify critical headways associated...

Measuring the traffic quality and congestion level is fundamental in highway engineering, several decades of studies research have pursued this specific objective, especially for freeways. Nowadays, smart technologies on personal devices information shared by users made available various online platforms that provide dynamic representations use road network. If, one hand, these tools a simple d...

In this paper we extend the Lighthill-Whitham-Richards kinematic wave traffic flow model to describe traffic with different types of vehicles, where all types of vehicles are completely mixed and travel at the same group velocity. A study of such a model with two vehicle classes (e.g., passenger cars and trucks) shows that, when both classes of traffic have identical free-flow speeds, the model...

Abstract Entry capacity is an important parameter for evaluating the roundabout performance. In general, entry influenced by three gap parameters: critical gap, follow-up time and minimum headway of circulating vehicles. These parameters certainly are correlated with driving behavior as well characteristics. this paper, video records two single roundabouts in state Qatar were used to estimate p...
