Abstract:
A first mobile monitoring system includes one or more mobile monitoring devices, a network, a server and a storage memory. The server is implemented to analyze the collected signals and the traffic information to identify at least one traffic flow according to travel routes of the one or more wireless devices; determine whether the identified at least one traffic flow exceeds an updating threshold based on the collected signals; derive at the server when the traffic flow exceeds the updating threshold, an updating priority indicating an order in which the traffic flows are processed based on the collected signals; and update a dynamic traffic transportation plan map based on the at least one traffic flow, the updating threshold and the updating priority.
Abstract:
Knowledge of the vehicle's lane position is required for several location-based services such as advanced driver assistance systems, driverless cars, and predicting driver's intent, among many other emerging applications. We present LaneQuest: a system and method that leverages the ubiquitous and low-energy inertial sensors available in commodity smart-phones to provide an accurate estimate of the vehicle's current lane. LaneQuest leverages the phone sensors about the surrounding environment to detect the vehicle's lane. For example, a vehicle making a right turn most probably will be in the right-most lane, a vehicle passing by a pothole will be in a specific lane and the vehicle angular velocity when driving through a curve reflects its lane. The ambiguous location, sensors noise, and fuzzy lane anchors; LaneQuest employs a novel probabilistic lane estimation algorithm. Furthermore, it uses an unsupervised crowd-sourcing approach to learn the position and lane span distribution of the different lane-level anchors.
Abstract:
A method and apparatus for retrieving and organizing geographical address information. Each physical address is assigned a unique code including symbols and alphanumeric characters. This unique code is the electronic address assigned to each physical address. Certain of the electronic addresses and the corresponding physical addresses are assigned aliases. The electronic addresses are assigned on a semi-permanent basis (i.e., the electronic addresses are not changed unless there is change to the physical location); whereas the aliases can be freely changed and reassigned among the electronic addresses.
Abstract:
First communication circuitry of a first device is made discoverable by a second device via a short-range wireless protocol. A device name for the first communication circuitry is set to a user identifier that is specific to a user of the first device. The second device discovers the first device and the user identifier is transmitted to the second device. A response message can also be included with the user identifier and can be appended to the user identifier. The second device stores the user identifier, and the response message if included, in a log to record a presence of the user of the first device within a range between the first and second devices of the short-range wireless protocol.
Abstract:
The present invention relates to receiving information of detected wireless electronic tags, comparing the received information to information stored in the server, and updating the information stored in the server based on the received information. Further, the invention relates to receiving a request regarding location information of an electronic wireless tag, determining whether identification information regarding the electronic wireless tag is available, and transmitting the identification information regarding the electronic wireless tag in response to the request regarding location information after determining that the identification information is available.
