The operation and transit of emergency vehicles on an automated highway system (AHS) designed under the control architecture proposed in the California Partners for Advanced Transit and Highways (PATH) program is described. The term emergency vehicles is used in a general sense to describe vehicles, such as police cars, ambulances, and tow trucks, that may service faults inside or outside the A...
Routing decisions affect everybody traveling on the roadways, but perhaps those decisions are never more important than for emergency responders. In a field where seconds count, getting lost or taking a sub-optimal route can mean the difference between life and death. Routing methods have advanced from hand drawn maps to smart phones with dynamic routing using GPS, and new data science methods ...
In emergency planning, consideration of emergency priorities is a necessity. This paper presents new formulations of the facility location problem (FLP) and vehicle routing problem with time windows (VRPTW) with considerations of priority. Our models ensure that higher priority locations are considered before the lower priority ones, for both facility and routing decisions. The FLP is solved us...
Telemonitoring during the golden hour of patient transportation helps to improve medical care. Presently there are different physiological data acquisition and transmission systems using cellular network and radio communication links. Location monitoring systems and video transmission systems are also commercially available. The emergency patient transportation systems uniquely require transmis...
The proposed RFID traffic control avoids problems that usually arise with standard traffic control systems, especially those related to image processing and beam interruption techniques. This RFID technique deals with a multivehicle, multilane, multi road junction area. It provides an efficient time management scheme, in which a dynamic time schedule is worked out in real time for the passage o...
Warning signals generated by sirens of authorized emergency vehicles should be audible and recognizable to all road users. Currently, there is no legislation in Poland defining sound pressure levels (SPLs) of audible warning signals generated by sirens of authorized emergency vehicles. Measured A-weighted SPLs of those signals range between 104 and 108 dB. While for road users, an audible warni...
In modern logistics operations, large-scale logistics companies, besides active participation in profit-seeking commercial business, also play an essential role during an emergency relief process by dispatching urgently-required materials to disaster-affected areas. Therefore, an issue has been widely addressed by logistics practitioners and caught researchers' more attention as to how the logi...
Two main streams of literature are relevant to the problem of considering server unavailability in emergency response systems. The first is that on the development of analytical models that allow for the calculation of measures related to server availability. The second is that related to location models for emergency service systems that incorporate such measures. Table A-1 summarizes the meth...
Adequate hazard perception and safe driving behavior in complex traffic situations are prerequisites for efficient emergency vehicle driving. In this field of interest, simulator training can be a useful tool to prepare young drivers to cope with the demands of real traffic conditions. In a pilot project, driving simulation as part of a comprehensive driver training program was implemented by t...
