A battery of 45 traffic cameras will be used as monitoring devices to ensure safety for the 43rd annual Honolulu Marathon this Sunday.

A coordinated plan is also in place between all city agencies to deal with any emergency, say marathon officials.

A spokeswoman for the Honolulu Police Department says the cameras have been a fixture since the 2013 Boston Marathon bombing.

This year, understandably, there is a heightened concern given the terrorist attacks in Paris and California.

When asked how prepared the city is in case an emergency situation arises, Honolulu Mayor Kirk Caldwell this week said, “as prepared as we can be.”

HPD will have a field operation center on the course, and there is an evacuation plan if necessary.

“So many times we see something that we may think doesn’t look right,” said Caldwell. “Your gut tells you something. Don’t just assume, well it’s probably okay. If you see something, say something. Call 911.”

The race starts at 5 a.m. on Ala Moana Boulevard near Piikoi Street and finishes at Kapiolani Park, a 26-mile journey that extends from downtown to Hawaii Kai.
