Abstract: Improved traffic management and control systems are widely reported to be cost‐effective investments. Simply retiming signals can provide significant benefits by reducing vehicle stops, travel times, and fuel consumption. ...

Abstract: Traffic monitoring and detection systems are important for constructing closed-loop traffic-signal control, freeway-control, and congestion-management systems. Most detection and monitoring systems depend on inductive ...

Abstract: State Transportation Departments nationwide manage huge amounts of information. Examples include geometric plans, sign inventories, maintenance records, engineering studies, and so on. In many cases, no indexing or archiving ...

Abstract: The formation of shockwaves demarking boundaries between different flow states in time-space domains has been well studied and documented in the literature. Previous research concentrated on theoretical and mathematical ...

Abstract: This paper presents a new methodology to measure delay at signalized intersections using linearly referenced global positioning system data. The methodology can be used to evaluate new models that estimate control delay ...

Abstract: Travel time has long been an important performance measure for assessing traffic conditions and the extent of highway congestion. However, recently, more and more attention has been given to understanding the uncertainty ...

Abstract: The design of signal timings for diamond intersections is well documented in the literature, and there are a variety of software packages to assist one in generating timing plans. However, the actual implementation of ...

Abstract: The civil engineering capstone senior design course at Purdue University involves all seniors in their last semester before graduation and is titled “Civil Engineering Design Project.” The course catalog describes it as ...

Abstract: Mechanically stabilized earth (MSE) walls are extensively used in civil infrastructure projects, particularly in areas with tight right-of-way constraints. Traditional geotechnical design of MSE walls includes internal and ...
