Query: Investigating Cybersecurity Issues In Active Traffic Management Systems   Active Traffic Management (ATM) systems have been introduced by
transportation agencies to manage recurrent and non-recurrent congestion. ATM
systems rely on the interconnectivity of components made possible by wired
and/or wireless networks. Unfortunately, this connectivity that supports ATM
systems also provides potential system access points that results in
vulnerability to cyberattacks. This is becoming more pronounced as ATM systems
begin to integrate internet of things (IoT) devices. Hence, there is a need to
rigorously evaluate ATM systems for cyberattack vulnerabilities, and explore
design concepts that provide stability and graceful degradation in the face of
cyberattacks. In this research, a prototype ATM system along with a real-time
cyberattack monitoring system were developed for a 1.5-mile section of I-66 in
Northern Virginia. The monitoring system detects deviation from expected
operation of an ATM system by comparing lane control states generated by the
ATM system with lane control states deemed most likely by the monitoring
system. In case of any deviation between two sets of states, the monitoring
system displays the lane control states generated by the back-up data source.
In a simulation experiment, the prototype ATM system and cyberattack monitoring
system were subject to emulated cyberattacks. The evaluation results showed
that when subject to cyberattack, the mean speed reduced by 15% compared to the
case with the ATM system and was similar to the baseline case. This illustrates
that the effectiveness of the ATM system was negated by cyberattacks. The
monitoring system however, allowed the ATM system to revert to an expected safe
state and reduced the negative impact of cyberattacks. These results illustrate
the need to revisit ATM system design concepts as a means to protect against
cyberattacks in addition to traditional system intrusion prevention approaches.
