Producing a Free–Flow Model for the First Chilean Freeway Using <i>Highway Capacity Manual 2000</i>
(American Society of Civil Engineers, 2005)The present work shows the results of a research study of the operation of the first interurban Chilean freeway [“Autopista del Sol,” -
Comparison of Control Delays from <i>CORSIM</i> and the<i> Highway Capacity Manual</i> for Oversaturated Signalized Intersections
(American Society of Civil Engineers, 2005)For oversaturated traffic conditions, control delays from -
Development of an Improved Cycle Length Model over the <i>Highway Capacity Manual 2000</i> Quick Estimation Method
(American Society of Civil Engineers, 2005)Chapter 16 of the -
Theoretical Analysis for Horizontal Curves Based on Actual Discomfort Speed
(American Society of Civil Engineers, 2005)The 2001 AASHTO publication -
Procedural and Operational Consequences of Navigational Equipment Outages: Exploration of Airport Performance
(American Society of Civil Engineers, 2005)This paper explores the impact of unscheduled navigational and surveillance equipment outages on airport performance during visual flight rules and instrument flight rules at San Francisco International Airport and Phoenix ... -
Use of Recurrent Markov Chains for Modeling the Crack Performance of Flexible Pavements
(American Society of Civil Engineers, 2005)Accurate prediction of the pavement crack condition is vital for pavement rehabilitation budget allocation. Due to largely nonlinear surface layer properties, randomness in the cracking mechanism, and the complexities ... -
Performance of Guardrail Systems Encased in Pavement Mow Strips
(American Society of Civil Engineers, 2005)Pavement mow strips are being used to combat growth of vegetation around guardrail posts. However, the effect of pavement post encasement on crashworthiness of strong post guardrail systems has not been investigated. In ... -
Work Zone Lengths for a Four-Lane Road with an Alternate Route
(American Society of Civil Engineers, 2005)Highway maintenance, like rehabilitation or resurfacing, on four-lane, two-way highways usually requires closing one or two lanes to set up a work zone. In this paper we evaluate several alternatives defined by the number ... -
Spatial and Temporal Variations in Axle Load Spectra and Impacts on Pavement Design
(American Society of Civil Engineers, 2005)The distribution of axle loads can vary geographically and seasonally; ignoring these variations may impact the accurate characterization of traffic and ultimately the design thickness of new and rehabilitated pavements. ... -
Discussion of “Multiple-Vehicle Origin–Destination Matrix Estimation from Traffic Counts Using Genetic Algorithm” by Seungkirl Baek, Hyunmyung Kim, and Yongtaek Lim
(American Society of Civil Engineers, 2005) -
Effects of Nonuniform Tire Contact Stresses on Pavement Response
(American Society of Civil Engineers, 2005)Since the 1960s, a uniform circular vertical contact stress has been used to model the tire/pavement interface in asphalt pavements. Recent experimental measurements show that this assumption cannot be used to model the ... -
Offsetting Opposing Left-Turn Lanes for Intersections on Horizontal Curves
(American Society of Civil Engineers, 2005)Left-turn vehicles need sufficient sight distance to decide when it is safe to turn left crossing the lane(s) used by the opposing traffic. Current AASHTO policy recommends that the adequacy of sight distance for left turns ... -
Feeder Bus Routes Generation within Integrated Mass Transit Planning Framework
(American Society of Civil Engineers, 2005)This paper discusses a model for developing optimal feeder bus routes, within integrated mass transit planning framework, for urban rail transit stations. The model is a part of the methodology to develop an effective and ... -
Effect of Bond Condition on Flexible Pavement Performance
(American Society of Civil Engineers, 2005)This paper summarizes a theoretical study undertaken to provide a deeper understanding of the consequences of poor bond on flexible pavement performance. Two different modeling approaches have been used. In the first, the ... -
Street Crossing by Sighted and Blind Pedestrians at a Modern Roundabout
(American Society of Civil Engineers, 2005)Pedestrian behavior and safety at roundabouts are not well understood, particularly for pedestrians with sensory or mobility impairments. A previous study in which participants indicated when they would cross suggested ... -
New Method to Assess Ride Safety on Uneven Element Pavements
(American Society of Civil Engineers, 2005)Stone element pavements are typical of many historical urban centers in Europe. Unfortunately, their deterioration due to traffic causes severely uneven road surfaces, compromising the safety of those who ride on two-wheeled ... -
Why Different Fatigue Lives? Answer Is in the Tomograms
(American Society of Civil Engineers, 2005)In this study, tomograms of bituminous mixtures with a photon energy -
Impact of Unsaturated Flow on Pavement Edgedrain Performance
(American Society of Civil Engineers, 2005)Water movement in pavement sections that included an edgedrain trench was investigated by means of numerical simulations that explicitly included unsaturated water flow. Most of the resulting water movement from infiltration ... -
Effects of Supersingle Tire Loadings on Pavements
(American Society of Civil Engineers, 2005)Due to their efficiency and economy, supersingle tires have gradually been replacing conventional dual tires in the trucking industry. According to recent studies, supersingle tires generate much higher vertical contact ... -
Life-Cycle Evaluation of Flexible Pavement Preventive Maintenance
(American Society of Civil Engineers, 2005)This study investigates the cost effectiveness of various levels of life-cycle preventive maintenance (PM) for three asphaltic concrete pavement functional class families. For each family, the effectiveness and cost ...
