CHAPTER 7. OBJECTIVE 4: ADVANCE THE STATE OF THE ART FOR MOBILE SENSING AND INTEGRATING VEHICLE DATA INTO ROAD WEATHER APPLICATIONS

Translating mobile and fixed observations to meaningful applications to solve problems for road weather management is the goal for this objective. Building from the growing number of States collecting mobile data, activities under this objective are geared towards showcasing applications that demonstrate the added value of mobile sensing in road weather management. The following performance measure (PM) tracks progress for this objective.

PM #14: Number of/percentage of responding agencies using mobile data-based applications in road weather management

As part of the Connected Vehicle Research track, the Federal Highway Administration (FHWA) Road Weather Management Program (RWMP) has been supporting the development of Vehicle to Infrastructure (V2I) applications that leverage mobile data and vehicle to infrastructure connectivity to support road weather management. This measure will begin tracking the number of agencies engaged in these activities. In the State departments of transportation (DOT) Survey, respondents reported on whether their agencies have developed applications or tools that rely on availability of real-time mobile data from vehicle fleets and/or vehicle-to-infrastructure connectivity. Figure 12 shows the extent to which State DOTs are developing applications or tools utilizing the availability of real-time data.

Summary

The results show that some State DOTs (23 percent) have developed applications that input real-time data from vehicle fleets, but fewer (5 percent) have developed applications that utilize data derived from vehicle fleets and vehicle-to-infrastructure connectivity. However, there is much potential for growth as expressed by significant interest from States that are considering the use of cutting-edge technologies to develop applications (58 percent).
