Abstract: The present disclosure is directed to methods and apparatus that monitor pedestrian traffic and that adjust the behavior of traffic signals at intersections and “walk”-“do not walk” indicators associated with particular crosswalks. Methods and apparatus consistent with the present disclosure may receive image or sensor data, may monitor the status of different traffic flow, and may adjust the timing of signal lights or walking indications as conditions change at an intersection. In certain instances, a traffic controller at one intersection may receive information collected by other traffic controllers along a set of streets that lead to a particular intersection. Traffic controllers that receive images of an intersection may identify partition the intersection into a set of safe and unsafe zones as those traffic controllers identify when pedestrians can safely cross an intersection.

Abstract: A system for determining a road frustration index value includes a vehicle and a user computing device within the vehicle and a remote computing system, where a telematics system associated with the vehicle senses a speed of the vehicle. The computing device calculates, in near real-time and based on vehicle speed information and the road class of one or more route segments of a travel route, a first frustration level value associated with the driver of the vehicle and identify, based on whether the first frustration level value meets a criterion, an alternate route segment having second frustration level value predicted to be less than the first frustration level value. The remote computing system receives information associated with the first route segment and the alternate route segment and calculates insurance cost based on the road frustration index values associated with a route traveled in the vehicle.

Abstract: A transport arrangement system operates to provide a service, which can receive a transport pool request from a rider. The transport pool request can specify a set of parameters, including a pickup location and a drop-off location.

Abstract: One embodiment of the present invention provides a system for communicating data using a socket interface with multiple transport layer implementations. During operation the system creates a socket which can be used with a set of transport layer implementations. Next, the system binds the socket to a local port without specifying a particular transport layer implementation. The system then receives a request to connect to a target port that is associated with a target address. Next, the system selects a protocol implementation from the set of transport layer implementations using the target port and the target address. The system then sends a connection request to the target port using the selected protocol implementation. Note that the present invention does not require changing a networking application because the transport layer implementation is selected automatically by the system, instead of requiring the application to possess the knowledge to select the appropriate transport layer implementation.
