This paper analyzes changes in passenger passenger activity and operating performance following implementation of a bus stop consolidation project at TriMet, the regional transit provider for the Portland, Oregon metropolitan area. The study makes extensive use of archived bus operations and passenger activity data from TriMet’s automated bus dispatching system. Focusing on one of the first rou...

1172 P in the vadose zone is nonuniform fl ow that can cause water and solute movement to bypass much of the soil matrix, often resulting in greater water fl uxes and shorter solute transit times than expected (Flury et al., 1994). Understanding preferential fl ow is crucial for quantifying aquifer susceptibility, defi ned as the inherent hydrogeologic properties that control the occurrence of ...

Transit Signal Priority (TSP) is an important element of Bus Rapid Transit (BRT) that involves coordinated efforts between transit vehicle detection systems, traffic signal control systems, and communication technologies. Successful deployment of TSP requires thorough laboratory evaluation through simulation before field implementation. This paper presents the development and application of a s...

Public transit plays a key role in shaping the transportation structure of large and fast growing cities. To cope with high population and employment density, such cities usually resort to multi-modal transit services, such as rail, BRT and bus. These modes are strategically connected to form an effective transit network. Among the transit modes, bus stops need to be properly deployed to mainta...

The characterization of congestion in communication systems is a pre-requisite for the definition of mechanisms that can be used in congestion control, with the goal to minimize its effects on the performance of distributed applications. In order for those mechanisms to work properly, there is the need to quantify congestion of services and systems. This paper proposes a scheme that enables the...

Ecohydrological processes are often evaluated by studying the fate of stable water isotopes. However, isotopic fractionation during evaporation is ignored or simplified in current models, resulting simulation errors that may be propagated into practical applications isotope tracing. In this study, we adapted and tested HYDRUS-1D model, a numerical model widely used to simulate variably-saturate...

In this paper, we are going to investigate the growth of the Iranian maritime transport with a focus mainly on the North - South transit Corridor, review of dry ports in order to support the Iranian container terminals at the south ports in order to increase the volume of container storages at the terminals. For the purpose of assessing the outcome of port operational management, the Balanced ...
