Full-Lane Coverage Micromilling Pavement-Surface Quality Control Using Emerging 3D Line Laser Imaging Technology
(American Society of Civil Engineers, 2014)Facing pavement preservation challenges as a result of funding shortages, the Georgia Department of Transportation (GDOT) has developed an innovative micromilling resurfacing method to cost-effectively preserve its pavements. ... -
Passenger Car Units at Different Levels of Service for Capacity Analysis of Multilane Interurban Highways in India
(American Society of Civil Engineers, 2014)Passenger car units (PCU) of different types of vehicles are required to convert a mixed traffic stream into a homogeneous equivalent, and thereby to express the mixed traffic flow in terms of equivalent number of passenger ... -
Methods for Defining Spatiotemporal Influence Areas and Secondary Incident Detection in Freeways
(American Society of Civil Engineers, 2014)The likelihood of the occurrence of secondary incidents is usually linked to primary incidents by using predefined spatial and temporal criteria. This paper extends past research on secondary incident detection by defining ... -
Experimental Test of an Articulated Lorry Swept Path
(American Society of Civil Engineers, 2013)The regulatory requirements limiting the physical dimensions of heavy vehicles and driving skills do not guarantee the feasibility of negotiating the tightest curves of compact roundabouts. The specific evaluations needed ... -
Free-Flow Travel Speed Analysis and Monitoring at the National Level Using Global Positioning System Measurements
(American Society of Civil Engineers, 2013)Among the main factors affecting road crash injuries, speed is considered as a leading cause and contributing factor. There are numerous studies linking travel speeds and road crashes. Hence, an essential part of road ... -
Roller-Integrated Compaction Monitoring for Hot-Mix Asphalt Overlay Construction
(American Society of Civil Engineers, 2013)This paper documents recent experiences using roller-integrated compaction monitoring (RICM) technologies on hot-mix asphalt (HMA) overlay construction projects in Iowa. Recently, new special provisions (SPs) to specifications ... -
Effects of Preoverlay Pavement Conditions and Preoverlay Repair Methods on the Performance of Asphaltic Concrete Overlays
(American Society of Civil Engineers, 2014)Asphaltic concrete overlay is a commonly used rehabilitation technology for existing asphaltic or concrete pavements. The existing pavements are often repaired prior to the placement of the overlay. Considering the significant ... -
Speed Stochastic Processes and Freeway Reliability Estimation: Evidence from the A22 Freeway, Italy
(American Society of Civil Engineers, 2013)In this paper, a criterion for predicting the reliability of freeway traffic flow is presented. The idea is based on an analysis of spot speed time series divided into sequences of events of random and homogeneous traffic ... -
Effects of Left-Turn Waiting Areas on Capacity and Level of Service of Signalized Intersections
(American Society of Civil Engineers, 2013)Transportation professionals in China have started using an unconventional left-turn waiting area design as an innovative approach to mitigate traffic congestion at signalized intersections. The waiting area is set up ... -
Predicting Aircraft Stopping Distances within an EMAS
(American Society of Civil Engineers, 2013)An overrun is an accident/incident in which an aircraft is unable to stop within the design runway length. To minimize the adverse consequences of an overrun, the Federal Aviation Administration (FAA) requires airports to ... -
Risk-Based Transit Schedule Design for a Fixed Route from the View of Equity
(American Society of Civil Engineers, 2013)This work proposed a model for transit schedule design by integrating the spatial-equity considerations into the slack-time setting problem. The proposed model can help to design a transit service for more equitable ... -
Development of Planning-Stage Models for Analyzing Continuous Flow Intersections
(American Society of Civil Engineers, 2013)Despite the increasing use of continuous-flow intersections (CFIs) to contend with the congestion caused by heavy through and left-turn traffic flows, a reliable and convenient tool for the traffic community to identify ... -
Comparison between GA and PSO in Analyzing Pavement Management Activities
(American Society of Civil Engineers, 2014)This paper demonstrates the application of particle swarm optimization (PSO) to the programming of pavement maintenance activities at the network level. Furthermore, the application of the PSO technique and its relevance ... -
Evaluation of Manual Traffic-Signal Control under Oversaturated Conditions Using Hardware-in-the-Loop Simulation
