RISEvaluation of Traffic Markings in Cold Regions
Publisher: American Society of Civil Engineers
Abstract: This paper summarizes a research project that evaluated the performance of traffic marking materials used in Alaska and other northwestern states. This study was conducted by reviewing existing reports, past studies, and ...
Line-Structured Light Rut Detection of Asphalt Pavement with Pavement Markings Interference under Strong Light
Publisher: ASCE
Abstract: The construction of highways has been well-developed worldwide. Meanwhile, the heavy traffic flow brings huge pressure on highway maintenance. Pavement rutting is one of the major pavement distresses and its detection has ...
Use of Recurrent Markov Chains for Modeling the Crack Performance of Flexible Pavements
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Capacity of U-Turn Movement at Median Openings on Multilane Highways
Publisher: American Society of Civil Engineers
Abstract: The goal of this study is to develop a procedure for estimating the capacity of U-turn movement at median openings on multilane highways. Data were collected at six selected median openings in the Tampa Bay area of Florida. ...
Operational Effects of U-Turns as Alternatives to Direct Left-Turns
Publisher: American Society of Civil Engineers
Abstract: This study analyzed the operational effects of a widely used access management treatment: using U-turns as alternatives to direct left-turns from driveways. Data were collected at 34 selected roadway segments in central ...
How Lane Arrangements on Freeway Mainlines and Ramps Affect Safety of Freeways with Closely Spaced Entrance and Exit Ramps
Publisher: American Society of Civil Engineers
Abstract: The number and arrangement of lanes on freeways are important considerations in freeway geometric design. The objective of this study is to evaluate the safety impacts of lane arrangements on freeway segments with closely ...
Performance Evaluation of No Track Thermoplastic Traffic Markings
Publisher: American Society of Civil Engineers
Abstract: No track thermoplastic is a relatively new thermoplastic traffic marking material which can be installed on newly constructed asphalt pavement shortly after finishing paving operations. The main objectives of this study ...
Pavement Cracking Detection and Classification Based on 3D Image Using Multiscale Clustering Model
Publisher: ASCE
Abstract: The use of three-dimensional (3D) pavement distress detection mechanisms has become a trend in pavement surface condition evaluation, including crack classifications and ratings. Inaccurate crack classification could affect ...
PCDNet: Seed Operation–Based Deep Learning Model for Pavement Crack Detection on 3D Asphalt Surface
Publisher: ASCE
Abstract: The detection of pavement crack plays a critical role in pavement maintenance and rehabilitation because pavement cracking is one of the most important indicators for the pavement condition evaluation, as well as an early ...
Procedure for Evaluating the Impacts of Indirect Driveway Left-Turn Treatments on Traffic Operations at Signalized Intersections
Publisher: American Society of Civil Engineers
Abstract: The use of nontraversable median cross sections and directional median openings has generated increased numbers of U-turning vehicles at signalized intersections. A procedure is needed to help transportation professionals ...
