Abstract
Floating car data (FCD) has been used to collect
traffic state information from a set of individual vehicles. Vehicles
are equipped with On Board Units (OBU) that collect different
measurements and the vehicle position and transmit the data to
a remote control center. In current implementations of FCD systems,
vehicle fleets use cellular connections for data transmission.
In this paper we consider an IEEE 802.11p-based Road Side Unit
(RSU) infrastructure for FCD collection. Installing RSUs in order
to acquire perfect coverage may prove to be a costly solution,
while gaps between the coverage areas will force data buffering
at OBUs. This might be a viable solution for delay-tolerant, but
not for safety-critical applications that require high data delivery
ratio. The goal of this paper is to study the trade-offs between
the size of the gaps between RSUs and other system parameters
such as data delivery ratio, data collection update interval and
size of measured data. We have proposed some heuristics that
can be used while deciding on the distance between neighboring
RSUs.
