Abstract
This project is a continuation of the original Integrated Mobile Observations (IMO 2.0) project that ran from January, 2013 through March, 2014. The Connected Driver: Integrated Mobile Observations, 2014-2015 project ran from April, 2014 through October, 2015. The main goal for the project was to show the applicability and capability of a smartphone based data collection system to provide accurate and timely micro-level road condition data to weather analysts in order to generate road condition warnings for drivers via electronic road signs, website, and mobile phone application (apps). The project employed an Android-based customized smartphone software program called DataProbe to gather information from the phone (date, time, latitude and longitude, altitude, number of satellites, speed, accelerometer data, and compass heading); the vehicle through its controller area network (CAN) (air and coolant temperature, odometer, barometer, tachometer, speedometer, throttle, brakes, anti-lock braking system (ABS), electronic stability control (ESC), engine traction control and braking traction control); and through external sensors, Surface Patrol, that measure road surface and air temperature, humidity, and dew point. When looking at the two IMO 2.0 projects combined over 31 months of data collection, vehicle operators drove 901,126 miles (363 gigabytes) and took 99,569 photos (45 gigabytes). Finally, the demonstration project at the 2014 ITS World Congress displayed the ability of UMTRI and NCAR researchers to combine the data collected from DataProbe sensors with an NCAR-developed Motorist Advisory Warning (MAW) phone application that delivered timely warnings to drivers of rain, slippery roads, and rough roads on their phone as well as on electronic signs in an area of 400 feet on the test track. This demonstration clearly showed that it is possible to provide micro-level weather reports in a timely manner. Project completion for this phase was October 31, 2015.Michigan Department of Transportationhttp://deepblue.lib.umich.edu/bitstream/2027.42/117546/1/103242.pdfDescription of 103242.pdf : Final repor
