The hours of service regulations of the department of transportation severely restrict the set of feasible driver schedules. So much so that establishing whether a sequence of full truckload transportation requests, each with a dispatch window at the origin, can feasibly be executed by a driver is no longer a matter of simple forward simulation. We consider this problem and prove that the feasi...

The Design Automation and Test in Europe (DATE) conference is the main European event in the field of Computer Aided Design (CAD) and testing. This outstanding event brings together researchers, users and vendors, as well as specialists in the design, test and manufacturing of electronic circuits and systems. DATE is a unification of the main conferences in the field and was built on the succes...

The advancements of GPS and GIS technologies provide new opportunities for investigating vehicle trip generation and destination choice at the microscopic level. This research models how land use and road network structure influence non-work, non-home vehicle trip generation and non-work destination choice in the context of trip chains, using the in-vehicle GPS travel data in the Minneapolis-St...

BACKGROUND Translating research evidence into clinical practice (TRIP) is an important initiative for health services so that care delivered is cost-effective, is efficient, and improves patient outcomes. Most TRIP studies have reported on disseminating and implementing clinical practice guidelines, protocols, or care pathways and have been undertaken in acute rather than community settings. ...

We present a constraint programming formulation for the elevator trip origin-destination matrix estimation problem, and study different deterministic and randomized algorithms to solve the problem. An elevator trip consists of successive stops in one direction of travel with passengers inside the elevator. It can be defined as a directed network, where the nodes correspond to the stops on the t...

The primary objective of the National Airspace System (NAS) is the transportation of passengers and cargo. Since passenger trip time performance is positively correlated with passenger satisfaction, airfare elasticity, and airline profits, it follows that the National Air Space (NAS) performance evaluation, modernization, and consumer protection should be based on passenger trip performance. Pu...

The return trip often seems shorter than the outward trip even when the distance and actual time are identical. To date, studies on the return trip effect have failed to confirm its existence in a situation that is ecologically valid in terms of environment and duration. In addition, physiological influences as part of fundamental timing mechanisms in daily activities have not been investigated...
