Development of a safe and easy Cabinet-in-the-loop Traffic Simulation System with ATC signal cabinet
(CILS-ATC) & Applications to Signal Projects and Education
by Pengfei “Taylor” Li - Mississippi State U.Cabinet-in-the-loop traffic simulation in essence adopts the whole set of traffic signal cabinet as a
control-interface-device (CID) during simulation rather than a special simplified device like in most
hardware(controller)-in-the-loop simulation (HILS). CILS’s advantage over HILS is that passing test in CILS
can guarantee real-world deployment for novel signal operations. However, CILS did not become
popular in the past due to high maintenance and (high-voltage) safety concerns within the cabinet. It
has been recently noticed that the latest ATC signal cabinet can greatly reduce the maintenance
requirement and totally remove the safety hazards within the cabinet. In this presentation, I will present
how to couple the latest ATC signal cabinet with VISSIM via ATC SIUs to create a safe and easy cabinetin-
the-loop simulation system, referred to as CILS-ATC. Additional discussions also include how to apply
the CILS-ATC to novel signal research, both in signal control and data collection, and how to facilitate the
signal education, especially exercises in cabinet telemetry, to make engineering students more prepared
for their future signal jobs.
Virtual Controller Interface Device
by Zong Tian - University of Nevada, RenoThis is a CID developed using NTCIP without a hardware device. It is fully functioning with Econolite’s
Colbat controllers and VISSIM. Besides the CID functions, I will briefly discuss an extended simulation
package called PASS – Physical Arterial Signal Simulation, which includes a signal timing development
interface and a physical small-scale arterial to demo signal control concepts.
Assessment of Eco-Driving under mixed traffic environment
by Brian Park – University of VirginiaWhile eco-driving concept has been introduced to achieve environmentally friendly driving behaviors,
the interactions between the human-driven vehicle and the automated vehicle (that perfectly follows
eco-driving guidance), and their impacts on eco-driving are not clear. We assessed the influence of the
automated leading vehicle and the eco-driving guidance on human driver’s eco-driving behavior using a
human-in-the-loop simulation (HILS) environment using PreScan software. Our results indicated that
both eco-driving guidance without automated leading vehicle and no-guidance with automated leading
vehicle improved over 6% fuel consumption when compared to the base case. This indicates the
presence of automated vehicle could help achieving eco-driving for none eco-driving guided vehicle.
