Abstract: Dilemma zone (DZ) is an area where drivers can neither stop comfortably nor cross safely when they are presented with a yellow indication at an intersection. The DZ problem is a leading cause for crashes at high-speed ...

Abstract: Freeway service patrol (FSP) is a low-cost but effective method to identify and clear incidents quickly on freeways, and it has been widely implemented in United States. Most of the related literature focuses on evaluating ...

Abstract: As the heating, ventilating, and air conditioning (HVAC) systems accounts for a major sector of energy consumption for commercial buildings, there has been a greater demand for improving the ...

Abstract: Calculation of time derivatives of refrigerant pressures is important for dynamic simulation of heat exchangers in vapor compression cycles, i.e., typically the condenser and evaporator. This ...

Abstract: Liquid nitrogen freezing technology is widely applied to reinforce the water-bearing ground around launching and receiving shafts of shield machines in subway tunnel construction projects. An improved liquid nitrogen ...

Abstract: This paper aims at proposing a calculation model to deal with the face stability of shield tunnels in unsaturated soil. Based on the existing results of centrifugal test and numerical simulation, a new failure mechanism ...

Abstract: Traffic-responsive plan selection (TRPS) control is one of the largely underutilized control features in National Electircal Manufacturers Association traffic controllers. This control feature allows the controller to ...

Abstract: During double-shield tunnel boring machine (DS-TBM) excavation of urban subway tunnels, backfilling with pea gravel and grouting is usually performed behind segment wall linings. However, insufficient pea gravel backfill ...
