The accuracy of the paramedic's estimated time until arrival (ETA) to an emergency department has never been studied. Two hundred and eighty paramedic runs were prospectively studied in a suburban, residency-affiliated emergency department. The average ETA was 7.39 +/- 3.72 minutes.

On Time-of-arrival Positioning in a Multipath Environment
IEEE Transactions on Vehicular Technology, 2005Wireless geolocation in a multipath environment is of particular interest for wideband communications and fast-developing ultrawideband (UWB) technologies. Conventional methods are solely based on first arriving signals. In this paper, it is investigated whether and under what conditions processing delay estimates of multipath components in addition to

Time-of-arrival estimation for blind beamforming
2013 18th International Conference on Digital Signal Processing (DSP), 2013Ad-hoc arrays formed by mobile devices are increasingly available to capture audio and video in social events. Using spatial signal processing algorithms, e.g., beamforming, with microphone signals of such arrays is hindered by the unknown locations of the devices and the lack of temporal synchronization between them. While self-calibration methods can

Integration Model for Estimated Time of Arrival
Proceedings of the 29th International Conference on Advances in Geographic Information Systems, 2021Estimated Time of Arrival (ETA) plays a vital role in many application scenarios. For example, in various scenarios such as online car-hailing order distribution, price estimation, mid-trip estimation, and route decision-making. Accurate arrival time estimation can help the platform improve efficiency.

The problem of finding proper quantal operators for the time of arrival, when the source is at infinite distance from the detector, is investigated. It is shown that at least two Hermitian operators can be constructed which, in the Hilbert space of positive energy spectrum, are self-adjoint.

Time-to-arrival estimations to simulated pedestrians
Accident Analysis & Prevention, 2020Driving a vehicle requires individuals' awareness of their surroundings to prevent collisions with other vehicles, objects, and pedestrians. While previous research has investigated time-to-arrival (TTA) in real-world and simulated driving situations, there is little information on how pedestrian reflectance and time of day impact TTA.
