Vehicular and Messaging Throughput Tradeoffs in Autonomous Highway Systems

DEPARTMENT RESEARCH FORUM

Emerging autonomous vehicular technology advances facilitate the development of intelligent traffic regulation systems, aiming to configure vehicular mobility patterns to enhance in-road safety and accommodate high rate transport of vehicle-to-vehicle messaging flows. To date, mechanisms that are implemented to regulate vehicular mobility and those employed to support communications of message flows across the highway, have been studied independently. In this talk, we investigate the synthesis and analysis of mechanisms that are used to regulate the mobility of highway vehicles, as they form distinct platoons, while also structured to disseminate high priority safety and lower priority status messaging flow at acceptable performance levels.

We identify desired configuration of platoon entities, and the underlying setting of the parameters of the spatial Time Division Multiple Access (TDMA) scheme, that satisfy the message delay limits required for the distribution of safety messages while attaining high throughput rates for the transport of status message flows. For each vehicular traffic congestion regime, we demonstrate the design options that are available in determining the system’s performance behavior, trading data messaging vs. vehicular traffic throughput rates.
