As others have said the red channel is overexposed. I experienced something similar when I took a photo of my grandson with his first buck kill. He was wearing a blaze orange cap and even though sitting in open shade the cap photographed as bright yellow in every exposure. I didn't notice until I got home so there was no opportunity to reshoot.
My solution was to take the best shot into Photoshop and change the color in the cap back to the correct shade. That edited photo is one of the family favorites.
In your cityscape it may be that the dynamic range between the stop lights and shadows is more than the camera can capture. Reducing the exposure in order to capture the red in the stoplights may result in loss of detail in the shadows which are IMO the more interesting parts of the photo. Were it my shot I think I would just edit the color of the lights.
