  Advancement in connected vehicle technology has created opportunities for
researchers to develop safety critical and assistive applications for drivers.
These applications do not only ensure drivers' safety and assistance services
but also benefit the environment by reducing fuel consumption and CO2 emission.
An intersection approach advisory system, which is one of the connected vehicle
applications, utilizes the dedicated short-range communications (DSRC)
technology for V2X communications and National Transportation Communications
for ITS Protocol (NTCIP) protocol reading SPaT data to provide intersection
related information to drivers. In this paper, we discuss such a system that
provides drivers the live signal information and recommends speeds through
visual and auditory means in a less distractive way to make informed decisions
before reaching to an intersection for different traffic scenarios. We also
discuss the in-depth analysis of the implementation issues and challenges of
such a system.
