Secondary Coordination at Closely Spaced Actuated Traffic Signals
Publisher: American Society of Civil Engineers
Abstract: This paper presents a method of addressing stochastic variation at closely spaced signalized intersections to provide secondary coordination to “minor” movements with significant traffic volumes. A neurofuzzy signal control ...
Proposed Model for Predicting Motorist Delays at Two‐Lane Highway Work Zones
Publisher: American Society of Civil Engineers
Abstract: Maintenance activity on two‐lane highways often requires the closure of one travel lane. Vehicles in both directions of travel are served via the one remaining lane. Under such conditions, alternating right of way into the ...
The Impact of Temperature on Major League Baseball
Publisher: American Meteorological Society
Abstract: ajor League Baseball is played from the beginning of April through the end of October each year, encompassing three of the four meteorological seasons: spring, summer, and fall. The 30 teams play in cities across the United ...
What Is an Effective Evacuation Operation?
Publisher: American Society of Civil Engineers
Abstract: Evacuation plans are traditionally based on empirical knowledge and local experience. Many studies are underway to improve and, even, optimize the process of evacuation planning and operations. To this end, a commonly ...
Retrieval of Three-Dimensional Raindrop Size Distribution Using X-Band Polarimetric Radar Data
Publisher: American Meteorological Society
Abstract: An improved algorithm based on the self-consistent principle for rain attenuation correction of reflectivity ZH and differential reflectivity ZDR are presented for X-band radar. The proposed algorithm calculates the optimum ...
Impacts of Intercycle Demand Fluctuations on Delay
Publisher: American Society of Civil Engineers
Abstract: This paper demonstrates that in addition to intracycle demand fluctuation, which is already a consideration in many delay models, intercycle demand variance also impacts average delay at signalized intersections. Webster-type ...
Optimization of Degradable Road Network Considering VMS Information and Heterogeneous ATIS Users
Publisher: American Society of Civil Engineers
Gray Areas in Isolated Intersection Control-Type Selection: Complementary Decision-Support Tool
Publisher: American Society of Civil Engineers
Abstract: The intersection control-type selections for future facilities can be determined by comparison of a common measure of effectiveness that is average control delay. However, rigid comparisons of such measures tend to mislead ...
Discover Spatiotemporal Association and Causation between Potholes and Flat Tire Frequency
Publisher: American Society of Civil Engineers
Abstract: This study attempts to untangle the association and causation between pavement potholes and vehicle flat tire frequency. To this end, the study collected pothole data from crowdsourced user-generated reports and extracted ...
Pacific Decadal Variability: The Tropical Pacific Mode and the North Pacific Mode
Publisher: American Meteorological Society
Abstract: Pacific decadal variability is studied in a series of coupled global ocean?atmosphere simulations aided by two ?modeling surgery? strategies: partial coupling (PC) and partial blocking (PB). The PC experiments retain full ...
