Alternative Information Signs: Evaluation of Driver Comprehension and Visual Attention
(American Society of Civil Engineers, 2016)The effectiveness of a traffic sign is collectively influenced by the sign’s understandability, legibility distance, glance legibility, and learnability; however, understandability has been repeatedly identified as one of ... -
Schedule-Based Rail Transit Path-Choice Estimation using Automatic Fare Collection Data
(American Society of Civil Engineers, 2016)This paper presents a schedule-based passenger’s path-choice estimation model for a multioperator rail transit network, using automatic fare collection (AFC) data from both entry and exit stations. By introducing the train ... -
Enhanced Decision-Making Framework Using Reliability Concepts for Freeway Facilities
(American Society of Civil Engineers, 2016)This paper presents a decision-making framework based on a travel time reliability methodology developed under the U.S. Strategic Highway Research Program. Existing methods consider a set of predefined prevailing conditions ... -
Quality of Private Sector Travel-Time Data on Arterials
(American Society of Civil Engineers, 2016)Accurate traffic state information is essential for both travelers and transportation agencies. In the past, traffic condition data were usually collected by a government agency using its own sensors. Recently, a number ... -
Effects of Missing Runway Performance Data on Maintenance Management Decision Making
(American Society of Civil Engineers, 2015)A problem commonly encountered in airport pavement management is how to deal with pavement condition and performance databases with various extents of missing data. While robust imputation techniques are now available to ... -
Effectiveness of Temporary Rumble Strips in Alerting Motorists in Short-Term Surveying Work Zones
(American Society of Civil Engineers, 2015)Many surveyors who work in/near live traffic encounter unique safety challenges as they are frequently exposed to fast moving vehicles. Unlike traditional work zones, safety countermeasures at surveying sites are usually ... -
Statistical Analyses of Field Serviceability of Throw-and-Roll Pothole Patches
(American Society of Civil Engineers, 2015)In order to evaluate the effectiveness of different pothole patching methods and materials, it is necessary to conduct a long-term field survey of patches installed at different environmental and traffic conditions. The ... -
Quantification of the Vertical Load Applied to the Pavement during Braking Maneuver of a Commercial Vehicle
(American Society of Civil Engineers, 2016)Front and rear axle braking performance in a vehicle is a well-documented subject in reference to longitudinal forces, but this statement is not valid for vertical forces. To analyze this behavior, a commercial vehicle ... -
Predictive Maintenance Model for Ballast Tamping
(American Society of Civil Engineers, 2016)In order to optimally schedule railway track maintenance operations, it is essential to accurately estimate future track conditions. This study proposes a railway track geometry degradation model that considers uncertainties ... -
Nonlinear Safety Analysis of a Running Road Vehicle under a Sudden Crosswind
(American Society of Civil Engineers, 2016)Threats of wind gusts on the safety of road vehicles have been reported around the world, and extensive studies have been carried out to find the accident speeds of road vehicles under a sudden crosswind. However, most ... -
Development of Speed Correction Factors Based on Speed-Specific Distributions of Vehicle Specific Power for Urban Restricted-Access Roadways
(American Society of Civil Engineers, 2016)Precise facility-specific speed correction factors (SCFs) are important parameters for direct and quick evaluation of the effect of traffic flow variations on vehicle emissions. However, the traditional method in developing ... -
A Model and Its Applications for Predicting Passing Rate at Passing Zones on Two-Lane Rural Highways
(American Society of Civil Engineers, 2016)Passing zones are designed to provide sufficient sight distance for fast vehicles to pass safely slow vehicles and contribute to operational efficiency of two-lane highways. However, lack of suitable models to predict ... -
Performance Evaluation and Correction Functions for Automated Pedestrian and Bicycle Counting Technologies
(American Society of Civil Engineers, 2016)Automated counting technologies are one of the fastest growing sources of data in the non-motorized transportation field. Although automated counts make it possible to collect data for longer time periods and to document ... -
Estimating Welfare Change Associated with Improvements in Urban Bicycling Facilities
(American Society of Civil Engineers, 2015)Prior research has focused on estimating the heath, air quality, safety, and congestion relief benefits of bicycling facilities. Bicycling facilities also provide bicyclists with a more enjoyable and safer feeling experience. ... -
Vehicle Speed and Acceleration Profile Study for Metered On-Ramps in California
(American Society of Civil Engineers, 2016)Ramp metering has been proven as an effective freeway-management strategy; however, one of the critical challenges in design and operation of ramp metering is the lack of up-to-date design guidance for acceleration lanes. ... -
Design of Turbo Roundabouts Based on the Rules of Vehicle Movement Geometry
(American Society of Civil Engineers, 2016)This paper describes a turbo roundabout design procedure based on the rules of design vehicle movement geometry. Previous studies carried out on various junction types have shown that this design approach ensures the usage ... -
State-of-the-Art Model to Evaluate Space Headway Based on Reliability Analysis
(American Society of Civil Engineers, 2016)Stipulating a space headway is a pivotal concern in traffic engineering. Although consideration of a larger headway leads to safer traffic movement, consideration for a smaller headway can serve more traffic volume, which ... -
An Optimization Strategy for Improving the Economic Performance of Heavy-Haul Railway Networks
(American Society of Civil Engineers, 2016)Optimization of wagon flow organization in heavy-haul loading areas is meaningful to develop a heavy-haul railway network and to improve transportation capacity. This paper proposes a multiobjective optimization of the ... -
Routing Trains with Consideration of Congestion-Induced Link and Node Delay
(American Society of Civil Engineers, 2016)North American heavy haul railroads are experiencing growth in traffic demand and increases in capacity constraints. An appropriate service-design process is thus crucial to allow for more effective network capacity planning ... -
