| Measuring Pedestrian Exposure Using Personal Electronic Devices
Behavioral Safety Research - NHTSA Battelle Memorial Institute - USD599,172.00 Active Lack of pedestrian exposure data makes it difficult to understand changes in pedestrian crash rates. While the changes may be due to increases or decreases in exposure, there are a variety of other factors that can influence the changes such as congestion, infrastructure, and pedestrian age and impairment. The inability to separate exposure changes from other factors impairs the ability to design effective countermeasures programs to reduce pedestrian crashes. This project would measure pedestrian exposure using personal electronic devices, such as cell phones or global positioning system (GPS) devices. The first phase of the project will identify existing sources of pedestrian location data to see if any of these sources can be mined for travel data and will develop an operational definition of pedestrian exposure. If possible, use the existing data to develop measure pedestrian exposure. If a good source of location data is not available, an app will be developed for participants to install on their personal cell phones or a device will be distributed to participants to obtain location data. The data will be anonymous and aggregated to discern potential exposure to vehicles. The next step of the project will be a small pilot study to recruit participants and collect exposure data.

| Impact of Lowering Speed on Pedestrian and Bicyclist Safety
Behavioral Safety Research - NHTSA University of North Carolina Highway Safety Research Center - USD385,673.00 Active The objective of this study is to assess the extent to which vehicle speeds, pedestrian/bicyclist crashes and conflicts and pedestrian/bicyclist injury severity change as a result of implementation of speed-related programs to improve pedestrian and bicyclist safety. The first phase of the study involves a program scan to determine localities that have implemented speed-related countermeasures on a large scale to increase pedestrian and bicyclist safety and that have data that can be used to evaluate these countermeasures before and after implementation. The study will use the data identified in the scan to determine the impact each speed-related countermeasure had on behavior outcomes (vehicle speeds, number of pedestrian/bicyclist crashes and conflicts, and pedestrian/bicyclist injury severity). The second phase of the study will be a prospective evaluation of the most effective speed-related countermeasures identified in the first phase. ID: 149785 |

| State-Level Roadside Study of Drug and Alcohol Driving
Behavioral Safety Research - NHTSA Dunlap and Associates, Incorporated - USD1,332,000.00 Active Roadside studies obtain substance use information from drivers randomly selected from the roadway � at the time of their driving event � thus providing the most accurate data on the use of alcohol and other drugs while driving. This project will enable the National Highway Traffic Safety Administration to assist States in conducting prevalence surveys of drug and alcohol use by drivers. ID: 149804 |

| Evaluation of a Change in a State's Blood Alcohol Content Per Se Law to an Alternative of 0.08
Behavioral Safety Research - NHTSA Dunlap and Associates, Incorporated - USD631,000.00 Active This project will evaluate the effects of a State lowering their Per Se limit to other than 0.08 BAC on alcohol-related crashes, impaired driving arrests, driver knowledge and awareness of the BAC Per Se Limit, perceived risk of detection and arrest for driving impaired by alcohol and the effects on alcohol sales.

| Integration of Innovative Sensing Technology and Data Analytics in Transportation Asset Management
University Transportation Centers - OST Virginia Tech Transportation Institute - USD300,000.00 Active Transportation asset management is an important tool to maintaining good physical status, quality service and trustworthy safety of infrastructure. Timely repair, rehabilitation, and preventive maintenance are critically important to maintaining such quality status and service, and prolonging service life at reduced costs. Infrastructure (bridges and pavements) degradation is a non-linear process and critical points where degradation rates change are important in decision making on rehabilitation. Nevertheless, it is challenging to predict the time of occurrence of such critical points. A number of modeling methods or models have been developed and yet the accuracy is very limited. Without reliable performance models, maintenance scheduling and life cycle cost assessments are not reliable and essentially just a mathematics manipulation. The limitations of such models are 1) models mainly based on mixture property testing in laboratories; 2) without considering the complicated loading and environmental conditions; 3) no integration of mix design lab test results and as constructed pavement properties; 4) having only relatively simple methods based on cause effect analysis of single or few causes. Recently a number of sensing techniques such as self-powered sensing, vibration sensor arrays and data analytics methods such as deep learning approaches have emerged and shown some promising features but not yet solidly developed to warrant implementation and realistic applications in asset management.
