摘要:
Disclosed is a vehicle identification method and system. The method includes: acquiring appearance information of an inspected vehicle; obtaining external features of the vehicle based on the appearance information; acquiring a transmission image of the vehicle and obtaining internal features of the vehicle from the transmission image; forming descriptions on the vehicle at least based on the external features and the internal features; and determining a vehicle model of the vehicle from a vehicle model databased by utilizing the descriptions. This method merges various types of modality information, especially introducing the transmission image, and combines the internal structure information with the appearance information, so that the present disclosure can identify a vehicle model more practically.

In many contexts, vehicles navigate routes while providing a service on behalf of a service provider, and with the assistance of global positioning systems (GPS) for navigation, routing, and/or vehicle tracking. In addition to identifying the location of the vehicle, devices with integrated GPS may also identify a population density (e.g., of individuals, cyclists, or other vehicles) within a vicinity of a location of the vehicle, which may caution a driver of high-population-density areas; may be used to assess a risk of the vehicle while navigating the route, and/or to suggest alternative routes; and/or to count the people who observe the vehicle navigating the route while performing the service. The GPS and/or population density estimator (e.g., a camera) are integrated with a car topper that is mounted atop the vehicle with a display that identifies the service, and optionally with a reversible mounting attachment and/or an integrated high-gain antenna.

A method for tracking non-motorized vehicle commuting activity includes providing a tracking system having a tag reader at a commute destination, wherein the tag reader is adapted to detect the presence of an RFID tag, and to generate and transmit a detection signal indicating a time of detection and one or more attributes of the detected RFID tag. The RFID tag is secured to a non-motorized vehicle used in commuting to the commute destination, and is secured in a manner to enable detection by the tag reader at the commute destination, and to prevent tampering therewith. Information obtained by the tracking system is accessible by one or more of a system administrator and a commuting participant.
摘要:
Traffic at an intersection, or other portion of a road, is detected, and the stop/go traffic signal apparatus at the intersection, or other portion is controlled based on vehicle types in the detected traffic. A vehicle type may be determined based on information collected by that vehicle's onboard telematics unit, or with a user's device in communication therewith. An input may be received from a user device, onboard the vehicle, to request changing the current stop/go configuration of the traffic signal. The request may be processed based on the determined vehicle type to determine whether or nor to change the traffic signal in response to the request. The request may be accompanied by an offer of money, and if the request is not granted, the user device may forward another request associated with a different offer.
摘要:
Systems and methods for obtaining data about road conditions as they pertain to an individual vehicle, using this information to build a model of vehicle behavior as a function of its environment, and aggregating information concerning multiple vehicles along with data from other sources in order to predict vehicle behavior in future environments.

We introduce a connected vehicles adaptive security signing and verification methodology. We also introduce an adaptive node filtering at receiver, using noise levels and received signal strength. This invention addresses two important pillars in connected vehicle technology and autonomous cars: The first one is related to the security 1609.2 format and its main two functions: signing and verification. The second one explains how the noise level and signal strength can be used to filter undesired connected nodes. In this presentation, we provide various examples and variations on these topics.

Aspects of the disclosure relate to an autonomous vehicle that may detected other nearby vehicles and identify them as parked or unparked. This identification may be based on visual indicia displayed by the detected vehicles as well as traffic control factors relating to the detected vehicles. Detected vehicles that are in a known parking spot may automatically be identified as parked. In addition, detected vehicles that satisfy conditions that are indications of being parked may also be identified as parked. The autonomous vehicle may then base its control strategy on whether or not a vehicle has been identified as parked or not.
摘要:
A radar transmitting unit Tx transmits a radio-frequency radar transmission signal from a transmission antenna which is inclined in the direction of a depression angle φ. A radar receiving unit Rx estimates the height and speed of a vehicle which travels on a road surface using a reflected wave signal from the vehicle. A template generating unit 19 generates a variation in a phase component of the reflected wave signal corresponding to N heights and speeds of the vehicle as N templates. N vehicle height/speed template correlation calculation units #1 to #Nrep calculate correlation on the basis of any one of the N templates and a correlation value between the reflected wave signal and a transmission code of the radar transmission signal.
摘要:
A system and method for monitoring a vehicle uses a wireless mobile device. The wireless mobile device, such as a cell phone, smart phone, PDA, etc., includes some of the hardware that could be utilized to monitor and analyze data and transmit the data (or summaries, statistics or analyses of the data) to a central server. This can greatly reduce the overall cost of the system. The data can be used to determine an insurance rate or as a speed probe for creating traffic maps, for example.

A mobile-device-based system for classifying a mode of transportation during a trip includes a mobile device including a location detection system and an accelerometer. The mobile device is configured to collect location data and acceleration data during the trip. The system also includes a data processing block configured to receive the location data from the mobile device, receive contextual data related to a plurality of transportation systems, and process the location data and at least a portion of the contextual data using a first transportation mode classifier associated with a first of the plurality of transportation systems and at least a second portion of the contextual data using a second transportation mode classifier associated with a second of the plurality of transportation systems. The data processing block is also configured to classify the mode of transportation during the trip and update the classifiers based on user input.
