Unified Transportation Sensor Data Format (UTSDF): Introduction
نویسنده
چکیده
Today’s transportation systems have been increasingly utilizing a wide range of sensors to monitor, control, and analyze many parts of transportation system components. The sensor usage has been further accelerated by the US DOT’s emphasis on Intelligent Transportation Systems (ITS) technologies in recent years. On the other hand, while the usage of sensors has increased, archiving (or saving) of the sensor data has not increased at the same rate [1]. In fact, only a small fraction of sensor data from the today’s transportation systems has been archived. For example, each intersection typically includes a number of vehicle detecting sensors to optimize the timing of the traffic controller, but the data is rarely archived.

Feasibility study for automatic calibration of transportation simulation models
This paper presents a high-tech solution to meet the challenges in calibrating transportation simulation models. Like any simulation software, model calibration prior to its application plays a crucial role in producing reliable results. However, transportation professionals face difficulties in performing the daunting tasks of calibrating a model for each transportation network design to satis...

We present a method of learning a Bayesian model of a traveller moving through an urban environment. This technique is novel in that it simultaneously learns a unified model of the traveller’s current mode of transportation as well as his most likely route, in an unsupervised manner. The model is implemented using particle filters and learned using Expectation-Maximization. The training data is...

Data Format for Storing ANT+ Sensors Data
Medical treatment of sudden and especially chronic diseases has become more expensive. People suffering from a variety of diseases had been traditionally treated in hospitals for a long time. Fortunately, the current situation has been changing also thanks to relatively cheap body sensors and development of systems for home treatment. It brings inconsiderable cost savings and improves patients?...
