69 INTRODUCTION The success of operating a drive-thru facility depends on queues and waiting times experienced by customers. Drivethru facilities are required to provide queuing areas that can hold the expected maximum queue length. Rates of arrivals and service times affect the required queuing areas for drive-thru facilities. Gattis recommended queuing areas for drive-thru facilities located ...

background: adverse effect of sun rays mainly uv ray on the human eye documented and protection of eyes is necessary using different methods such as, sun glasses. sunglasses are designed in different colors. the aim of this study was evaluation of the effect of different colors of sunglasses on the visual acuity, contrast sensitivity, stereopsis and color vision. methods: 81 normal subjects wer...

Traffic flow is the study of interactions between vehicles, drivers and related infrastructure with the goal of understanding and developing an efficient road network. A number of devices have been implemented for monitoring traffic flow such as magnetic strips and radar detectors (Haidarian-Shahri et al. (2007)). All these devices have served for a very specific purpose. However, they do not p...

We propose a general model to derive lane-changing rules for discretionary and mandatory lane changes for a wide class of car-following models. Both the utility of a given lane and the risk associated with lane changes is determined in terms of longitudinal accelerations calculated with the microscopic traffic models. This allows for the formulation of compact and general safety and incentive c...

A framework for integrated driving behavior modeling, based on the concepts of short-term goal and short-term plan is proposed. Drivers are assumed to conceive and perform short-term plans in order to accomplish short-term goals. This behavioral framework captures drivers' planning capabilities and allows decisions to be based on anticipated future conditions. An integrated driving behavior mod...

PIC 18F series microcontroller is used for control of signals to a specific time using port lines. In this contest we choose the Bicolor LEDs with Red and Green. The colors of the signals are illuminated by programming in the microcontroller. The aim of this paper is to generate three colors on a single traffic light instead of using three different color traffic signal lights. The purpose of t...

Left-turn lanes at nonsignaiized intersections on two-lane interurban roads reduce the number of traffic interferences and increase the level of service for the through traffic. These improved conditions result from the opportunity turning vehicles have to decelerate and wait in a separate lane for a suitable crossing gap. Decreasing the number of interferences to through traffic reduces the nu...

One of the riskiest maneuvers that a driver has to perform in a conventional highway system is to merge into the traffic and/or to perform a lane changing maneuver. Lane changing/merging collisions are responsible for one-tenth of all crash-caused traffic delays often resulting in congestion. Traffic delays and congestion, in general, increase travel time and have a negative economic impact. In...

Drivers continuously evaluate the surrounding traffic and the roadway environment, and make decisions about lanes and travel speed. The objective of this thesis is to develop a lane changing model that can be used in microscopic traffic simulation models to capture drivers' lane changing behavior. Lane change is modeled as a sequence of four steps: decision to consider a lane change, choice of ...
