establish and administer a transit signal priority program for
5
public transportation vehicles in the metropolitan region.

Nothing in this Section authorizes the installation,

modification, operation, or maintenance of traffic control

devices except in accordance with the Illinois Vehicle Code,
14
the Illinois Manual on Uniform Traffic Control Devices, and
15
applicable federal requirements.

18
signal preemption, or other safety-critical signal operations
19
required by law or engineering standards.

For highways and streets under the jurisdiction of the

signal priority implementation.

feasible, cost-effective, and consistent with applicable
15
safety and traffic control standards, the Department shall

incorporate transit signal priority accommodations into the
17
project design.
