Modeling Driver Behavior and Safety on Freeway Merging Areas
(American Society of Civil Engineers, 2008)Access to freeways is provided through interchanges to maintain the design concept of uninterrupted traffic flow. Therefore, provision of an appropriate entrance ramp and acceleration lane geometry that allows the entering ... -
Combining Climate, Crash, and Highway Data for Improved Ranking of Speed and Winter-Weather Related Crash Locations in Oregon
(American Society of Civil Engineers, 2008)In recent years, the techniques for screening transportation networks to identify high crash locations have become more sophisticated with significant data requirements. This paper presents the results of an empirical ... -
Safety Analysis of Florida Urban Limited Access Highways with Special Focus on the Influence of Truck Lane Restriction Policy
(American Society of Civil Engineers, 2008)Detailed modeling of traffic crashes occurring on urban limited access highways in Florida was conducted to determine the influence of various geometric and traffic variables on crash occurrence with special emphasis on ... -
Robust Scheduling of Truck Arrivals at Marine Container Terminals
(American Society of Civil Engineers, 2008)The use of a truck appointment system is gaining momentum in the marine container industry. It is used to regulate the number of trucks that can enter the terminal. Terminals employing appointment systems put a cap on the ... -
Finite-Element Modeling of Aboveground Wavy Pipelines: Practical Approach
(American Society of Civil Engineers, 2008)This paper presents how finite-element analysis can be used as a tool to design aboveground wavy pipeline layouts in order to avoid any excessive lateral movements under normal operating conditions. The paper also presents ... -
Web-Based Guide to Transportation Benefit-Cost Analysis
(American Society of Civil Engineers, 2008)Originally begun as an ASCE committee activity, this comprehensive on-line guide to benefit-cost analysis (BCA) was completed under the sponsorship of the Office of Transportation Economics of the California Department of ... -
Treating Uncertain Demand Information in Origin–Destination Matrix Estimation with Traffic Counts
(American Society of Civil Engineers, 2008)This paper investigates the problem of estimating dynamic origin–destination -
Measuring Control Delay Components Using Second-by-Second GPS Speed Data
(American Society of Civil Engineers, 2008)High-resolution vehicle speed profiles obtained from sophisticated devices such as global positioning system (GPS) receivers provide an opportunity to accurately measure intersection delay, composed of deceleration delay, ... -
Signalized Intersection Analysis and Design: Implications of Day-to-Day Variability in Peak-Hour Volumes on Delay
(American Society of Civil Engineers, 2008)Traffic signal timing plans are typically developed on the basis of turning movement traffic and pedestrian volume counts aggregated to 15-min intervals and obtained over a 4 or -
Large-Scale Microscopic Simulation: Toward an Increased Resolution of Transportation Models
(American Society of Civil Engineers, 2008)Recent years have witnessed an interest in increasing the resolution of transportation models to allow them to better address emerging transportation issues, such as concerns about emissions, air quality, and emergency ... -
Evaluation of Dynamic Passing Sight Distance Problem Using a Finite-Element Model
(American Society of Civil Engineers, 2008)Sufficient passing sight distance is an important control for two-lane rural highway design to minimize the possibility of a head-on collision between passing and opposing vehicles. Traditionally, passing zones are marked ... -
Toward Roundabout Accessibility—Exploring the Operational Impact of Pedestrian Signalization Options at Modern Roundabouts
(American Society of Civil Engineers, 2008)This paper explores the use of pedestrian signalization options for crosswalks at one- and two-lane roundabouts to enable these facilities to be accessible to pedestrians with vision impairments. Motivated by uncertainties ... -
Freeway Work-Zone Crash Analysis and Risk Identification Using Multiple and Conditional Logistic Regression
(American Society of Civil Engineers, 2008)Work-zone safety continues to be a priority and a concern for the Federal Highway Association as well as most state departments of transportation. The main objective of this study is to uncover work-zone freeway crash ... -
Evaluation of Life-Cycle Cost Analysis Practices Used by the Michigan Department of Transportation
(American Society of Civil Engineers, 2008)Life-cycle cost analysis (LCCA) has become a common practice in road construction at the state level during the past decade in the United States. It enables pavement engineers to conduct a comprehensive assessment of ... -
Optimal Asphalt Pavement Design Considering Cost and Reliability
