Abstract: Modern infrastructure systems, ranging from transportation to water and sewer systems, are becoming increasingly dependent on software. The role it plays in these systems is primarily to integrate and manage elements that ...

Abstract: IntelliDrive, the integration of vehicles and the infrastructure through wireless communication, has generated great interest in the transportation community. It is widely expected ...

Abstract: Evaluation of travel-time data quality from traveler information systems (TISs) is a critical need for many transportation agencies. To measure data quality, observations of ground-truth travel time must be collected on ...

Abstract: The capability to forecast traffic volume in an operational setting has been identified as a critical need for intelligent transportation systems (ITS). In particular, traffic volume forecasts will support proactive, dynamic ...

Abstract: The challenge of integrating multiple computer applications and systems is common in civil engineering. For example, civil engineers are working to integrate geographic information systems, database management systems, and ...

Abstract: Civil engineers have introduced sophisticated sensing and control systems to better operate infrastructure systems, resulting in what are termed

Abstract: The ability to measure or estimate accurate speed data are of great importance to a large number of transportation system operations applications. Estimating speeds from the widely used single inductive loop sensor has ...

Abstract: Traffic flow rate, the equivalent hourly rate of vehicles passing a point during a given time interval, is a fundamental measure of traffic status that plays a critical role in many aspects of transportation engineering. ...

Abstract: Incidents, defined as unplanned events that temporarily reduce roadway capacity, contribute significantly to urban freeway congestion. Transportation agencies have developed incident management programs in order to support ...
