RISSpatial Transferability Testing of Dummy Variable Winter Weather Model Using Traffic Data Collected from Five Geographically Dispersed Weigh-in-Motion Sites in Alberta Highway Systems
Publisher: ASCE
Abstract: It has been an engineering practice that highway agencies collect traffic data using highway traffic monitoring techniques such as permanent traffic counts (PTCs) and weigh in motion (WIM). This research used the WIM traffic ...
Developing a Risk Assessment Model for a Highway Site during the Winter Season and Quantifying the Functional Loss in Terms of Traffic Reduction Caused by Winter Hazards Conditions
Publisher: ASCE
Abstract: This paper introduces a methodology to quantify traffic change triggered by the combined effect of weather hazards based on winter weather hazards models. The winter weather hazards models for three vehicle types were ...
Diagnosing the Effects of Weather Factors on Cold Region Highway Traffic Operation with Two Layers of Nonparametric Statistical Analysis
Publisher: ASCE
Abstract: Highway agencies use significant financial resources to operate traffic monitoring programs. Conventional traffic monitoring practices are operated only during weather-permissible periods, leading to inefficient traffic ...
Sustainability Enhancement of Inclement Weather Dummy Factor Model: A Study of Big Traffic Data in Canada
Publisher: American Society of Civil Engineers
Abstract: Transportation agencies in cold regions are tasked with developing traffic models and verifying their accuracy. Few prior studies have examined the spatial transferability of model coefficients across different types of ...
Development and Performance Assessment of Winter Climate Hazard Models on Traffic Volume with Four Model Structure Types
Publisher: ASCE
Abstract: Much previous research recognizes hazardous winter-weather conditions such as heavy snowfall and cold temperatures as affecting the change in traffic volume, and modeling has been used to simulate variations in traffic ...
Developing Cold Region Winter Weather Traffic Models and Testing Their Temporal Transferability and Model Specification
Publisher: American Society of Civil Engineers
Abstract: It is well known from past studies that inclement winter weather conditions such as heavy snowfall and harsh temperature affect the variation of traffic volume. In order to quantify the change in traffic volume caused by ...
Statistical Investigations of Snowfall and Temperature Interaction with Passenger Car and Truck Traffic on Primary Highways in Canada
Publisher: American Society of Civil Engineers
Abstract: Winter weather conditions such as extremely cold temperatures, heavy snowfall, and high wind chills are common occurrences in Canada. Impacts of such adverse weather conditions on total highway traffic volume have been the ...
