  In this demonstration proposal, we present a prototype of a rapidly
deployable and cost-effective railroad crossing early warning system integrated
with the railway system. Specifically, the proposed demonstration deal with the
safety applications based on dedicated short range communications (DSRC)
protocol and devices using our different antennas. We will demonstrate the
feasibility and advantages of our proposed system, including the antenna
design, system deployment, the over-the-air transmission, and the software
applications that we developed for the end users.
