Sun Glare Impacts on Freeway Congestion: Geometric Model and Empirical Analysis
(American Society of Civil Engineers, 2012)In this paper, a geometric model for predicting locations and times where sun glare has the potential to affect drivers on roadways was developed. Existing or prospective highway alignments can be considered. The method ... -
Freeway Recurrent Bottleneck Identification Algorithms Considering Detector Data Quality Issues
(American Society of Civil Engineers, 2012)Computer algorithms used to identify recurrent freeway bottlenecks have been studied since the deployment of loop detecting systems. Such algorithms automatically analyze the archived loop detector data and identify potential ... -
Planning of Fixed-Route Fixed-Schedule Feeder Service to Bus Stops in Rural India
(American Society of Civil Engineers, 2012)Rural feeder service between villages and bus stops is largely a missing component in developing countries such as India. Traditionally, planning of rural feeder service has been carried out without due consideration to ... -
Traffic Flow Theory–Based Stochastic Optimization Model for Work Zones on Two-Lane Highways
(American Society of Civil Engineers, 2012)Road maintenance is essential to ensure a safe and efficient transportation system. Unfortunately, work zones can give rise to significant delays to road users. In this paper, two major limitations in the current work zone ... -
Integrated Heteroscedasticity Test for Vehicular Traffic Condition Series
(American Society of Civil Engineers, 2012)Because of the growing awareness of the importance of the traffic condition uncertainty-related studies, traffic condition uncertainty modeling is gaining increasing attention from the transportation research community. ... -
Predicting Lane Utilization and Merge Behavior at Signalized Intersections with Auxiliary Lanes in Buffalo, New York
(American Society of Civil Engineers, 2012)Although auxiliary through lanes (ATLs) are often used to increase the capacity at signalized intersections, their utilization by motorists tends to be significantly lower than continuous through lanes (CTLs). This study ... -
Throughput Capacity Estimation for Convoy Movement in Linked Roads
(American Society of Civil Engineers, 2012)This research is aimed at finding the throughput rate of convoy movement in a transportation network. The primary goal of the study is first to find the throughput rate that will facilitate an estimate of the time to ... -
Geogrid-Reinforced Low-Volume Flexible Pavements: Pavement Response and Geogrid Optimal Location
(American Society of Civil Engineers, 2012)This article discusses the geogrid’s potential to reduce granular base shear flow. Researchers have previously acknowledged the geogrid’s potential to enhance the performance of roadways, but this study goes further to ... -
Time Series Analysis and Models of Freeway Performance
(American Society of Civil Engineers, 2012)This paper describes a study whose primary purpose is to better understand the relationship between freeway traffic flow and speed. Incidents of recurrent and nonrecurrent congestion were encountered at six radar collection ... -
Thickness Design of PCC/FBC Composites for Secondary/County Roads
(American Society of Civil Engineers, 2012)Tests were conducted in the laboratory and field to determine the extent to which fluidized bed combustion (FBC) spent bed and pulverized coal combustion (PCC) fly ash, by products of the coal industry, can be used in ... -
Traffic Signal Optimization with Greedy Randomized Tabu Search Algorithm
(American Society of Civil Engineers, 2012)Although advanced technologies, such as detection techniques and controllers, have been incorporated within Advanced Traffic Management Systems (ATMS), pretimed signal control still plays an important role in traffic control ... -
Unified Mechanistic Approach for Modeling Tests of Unbound Pavement Materials
