RISLarge-Scale Loop Detector Troubleshooting Using Clustering and Association Rule Mining
Publisher: ASCE
Abstract: The archived data from traffic sensors are used in a wide range of traffic management applications. However, missing or invalid data are becoming an important concern. This study proposes a systematic approach to identify ...
Link-Journey Speed Estimation for Urban Arterial Performance Measurement Using Advance Loop Detector Data under Congested Conditions
Publisher: American Society of Civil Engineers
Abstract: Travel speed ties directly to travel time, so it is an important measure for quantifying arterial performance. However, accurately estimating link travel speed for urban arterials is difficult because of traffic fluctuations ...
Incorporating Mode Choices into Safety Analysis at the Macroscopic Level
Publisher: ASCE
Abstract: Investigating the contributing factors to aggregated crashes as a function of trip variables combined with details of their purpose and transportation modes is important in the planning stage of a transportation network. ...
A Multisource Data Approach for Estimating Vehicle Queue Length at Metered On-Ramps
Publisher: ASCE
Abstract: Queue length information is a critical input for ramp metering management. Based on accurate and reliable queue length, the inflow rate can be optimized to maximize the benefit of ramp metering. This paper proposes a queue ...
Large-Scale Freeway Traffic Flow Estimation Using Crowdsourced Data: A Case Study in Arizona
Publisher: American Society of Civil Engineers
Abstract: Vehicular flow rate is an essential measure commonly collected by inductive-loop detectors for transportation agencies to evaluate freeways and highways. Loop detectors are typically located in urban areas due to installation ...
Fuzzy Logic–Based Mapping Algorithm for Improving Animal-Vehicle Collision Data
Publisher: American Society of Civil Engineers
Abstract: Animal-vehicle collisions (AVCs) cause hundreds of human and wildlife animal fatalities and tens of thousands of human and wildlife animal injuries in North America. It is estimated that AVCs cause more than $1 billion in ...
Handling Imbalanced Data for Real-Time Crash Prediction: Application of Boosting and Sampling Techniques
Publisher: ASCE
Abstract: With a growing number of intelligent transportation system sensors and the networkwide deployment of those across the nation’s roadway facilities, current research and practices should concentrate on more proactive safety ...
Evaluation of Arterial and Freeway Interaction for Determining the Feasibility of Traffic Diversion
Publisher: American Society of Civil Engineers
Abstract: Traffic congestion is a common phenomenon in our daily lives that greatly costs society. A better understanding of the interaction between freeways and arterial streets may help traffic engineers and researchers improve ...
Climate Change Influence on Priority Setting for Transportation Infrastructure Assets
Publisher: American Society of Civil Engineers
Abstract: Transportation infrastructure could be vulnerable to local manifestations of global climate change, such as storm frequencies and durations of seasons. To adapt, transportation agencies need methodologies for reprioritizing ...
