Autonomous Vehicle Guidance Evaluation
No full textThis report provides an overview of autonomous vehicle technology, specifically focusing on
sensing and control technologies. It resulted from safety issues at the Mn/ROAD high-load,
low-volume pavement test facility. Appropriate technology helps ensure the safety of the
truck driver that provides loads to the pavement and the safety of traffic on 1-94.
Researchers currently are working to provide a semi tractor capable of driver-supervised
autonomous operation at the Mn/ROAD facility. Such a driver-supervised system will allow
the truck driver to monitor the operation of the automatic control system actively guiding the
truck and will allow the driver to take control from the control computer when desired.Minnesota Department of TransportationShankwitz, Craig; Donath, Max. (1995). Autonomous Vehicle Guidance Evaluation. Retrieved from the University Digital Conservancy, https://hdl.handle.net/11299/155349
Collision Avoidance: Smart Trucks on Rural Roads
No full textWith interest in collision avoidance technology for highway vehicles on the rise, this report
presents an overview of current collision avoidance technology, the technical work required to
bring these systems to a commercially viable product, and the societal issues that need
addressing before wide-scale deployment can occur. Many questions remain about the benefits
of deploying such systems, the costs, the effect of these systems on drivers, and the steps
necessary to effectively regulate vehicles equipped with such systems.
In addition to technical aspects, the report also discusses the issues that society will face
during development and deployment of these systems, which may prove bigger impediments to
deployment than technical issues. The report also recommends a research plan to perform
fair, unbiased evaluations of emerging collision avoidance technology.Minnesota Department of TransportationShankwitz, Craig; Donath, Max. (1995). Collision Avoidance: Smart Trucks on Rural Roads. Retrieved from the University Digital Conservancy, https://hdl.handle.net/11299/155350
Differential GPS Based Control of a Heavy Vehicle
No full textThis report describes the development of technologies that safely steer a vehicle if the vehicle's driver becomes incapacitated.
A Differential Global Positioning System (GPS) senses the vehicle's position and velocity. This method seems to offer adequate precision with a low-enough infrastructure cost to make the system practical in most rural settings. Researchers used a heavy vehicle -- a class 8 truck tractor -- partly because of the most favorable economics associated with installation of this type of system on a commercial vehicle, and partly because of the commercial driver's higher exposure to conditions that engender drowsy driving.
This research examines two potential applications of the steering, throttle, and brake controllers. The first, a virtual rumble strip, vibrates the wheel whenever the vehicle drifts out of its lane. The second, a system senses the erratic steering that presages loss of consciousness, and then takes control of the vehicle, pulling it over to a safe stop.GuidestarAlexander, Lee; Donath, Max.

MIMIC Sensor Technology for Highway Vehicle Applications: Potential and Challenges for the Future
No full textRecent advances in MIMIC (MIllimeter Monolithic Integrated Circuit) radar technology play
an important role in the development of automated highway systems and automated vehicle
control systems. This report presents results of a preliminary investigation into MIMIC-based
automotive radar technology and makes recommendations for hardware evaluation.
MIMIC technology integrates much of the radar transmitted, receiver, and signal processing
hardware onto a one- or two-piece chip set. Massive integration leads to lower manufacturing
costs and lower product costs. Moreover, this integration reduces the size of hardware,
allowing the radar components to be installed in the vehicle without the need for significant
modifications. As radar systems become smaller and cheaper, the demand for these systems
will increase.
Radar systems affect both the vehicles so equipped and other vehicles within a reasonable
proximity. Before vehicles equipped with radar systems travel on public roads, their effects on
traffic flow and highway safety must be investigated so that proper regulations can be
developed and enforced.Minnesota Department of TransportationShankwitz, Craig; Donath, Max. (1995). MIMIC Sensor Technology for Highway Vehicle Applications: Potential and Challenges for the Future. Retrieved from the University Digital Conservancy, https://hdl.handle.net/11299/155366
The Virtual Bumper: A Control Based Collision Avoidance System For Highway Vehicles
No full textThis report summarizes research on a new collision avoidance strategy, the 'virtual bumper.' The research involves development and simulation testing of the virtual bumper, a two-dimensional control strategy that provides steering, throttle, and braking actuation to maneuver a vehicle in a dynamic environment with the goal of avoiding obstacles and other vehicles. The concept applies to both normal and emergency driving conditions. Under all circumstances, the virtual bumper incorporates vehicle dynamic limits to ensure that the control commands are within safe levels. The virtual bumper will attempt to avoid a collision and will, at least, minimize the magnitude of an unavoidable collision. To test the functionality of the virtual bumper, researchers evaluated several driving scenarios. The scenarios consider both normal driving situations and emergency driving conditions. The normal driving scenarios demonstrated that the control algorithm operates the vehicle similar to the way a human would. This is important because a comfortable and predictable (i.e., intuitive) system response is required for achieving driver acceptance. The emergency scenarios demonstrated that the strategy is capable of reacting appropriately while maintaining safe acceleration/deceleration levels for the vehicle. This evaluation showed that the virtual bumper can provide safe vehicle control for a broad range of driving situations.Minnesota Department of TransportationSchiller, William; Donath, Max. (1997).

Minnesota Department of Transportation Rural Intersection Conflict Warning System (RICWS) Reliability Evaluation
No full textThe Minnesota Department of Transportation (MnDOT) developed the Rural Intersection Conflict Warning System (RICWS) Deployment project to reduce crashes at stop-controlled intersections. It is a statewide, Intelligent Transportation Systems project that will deploy intersection conflict warning systems at up to 50 rural, stop-controlled intersections. These systems will address crashes at stop-controlled intersections by providing drivers - on both the major and minor road - with a dynamic warning of other vehicles approaching the intersection. The first RICWS site, Trunk Highway 7 and Carver County CSAH 33, was evaluated for a period of 34 days to demonstrate the reliability of the system. During this period, the RICWS signs, beacons, and any other displays were covered and unavailable for driver interaction. The University of Minnesota installed a portable Intersection Surveillance System (ISS) and collected data from the RICWS as well as from the ISS. The data collected from the RICWS was validated against data recorded by the ISS in order to determine the accuracy and reliability of the RICWS. The RICWS was determined to have an activation rate of 99.98%, and meets the MnDOT specification of 99.95% sign activation rate. Sign activations were also validated using video captured at the site and a sample of times for valid activations and valid periods when the sign was inactive were recorded.Menon, Arvind; Donath, Max.

Investigating the Effectiveness of Using Bluetooth Low-Energy Technology to Trigger In-Vehicle Messages in Work Zones
No full textIn order to reduce risky behavior around workzones, this project examines the effectiveness of using invehicle messages to heighten drivers’ awareness of safety-critical and pertinent workzone information. This investigation centers around an inexpensive technology based on Bluetooth low-energy (BLE) tags that can be deployed in or ahead of the workzone. A smartphone app was developed to trigger nondistracting, auditory-visual messages in a smartphone mounted in a vehicle within range of the BLE workzone tags. Messages associated with BLE tags around the workzone can be updated remotely in real time and as such may provide significantly improved situational awareness about dynamic conditions at workzones such as: awareness of workers on site, changing traffic conditions, or hazards in the environment. Experiment results indicate that while travelling at 70 mph (113 km/h), the smartphone app is able to successfully detect a long-range BLE tag placed over 410 feet (125 meters) away on a traffic barrel on a roadway shoulder. Additional experiments are being conducted to validate the system performance under different roadway geometry, traffic, and weather conditions.Liao, Chen-Fu; Donath, Max. (2016).
