I attempted the repair tool and it did repair a couple of geometric line a radii issues on the traffic signals and ran the model and received the invalid geometry error. I also turned off shared topology and used bonded contacts instead and ran the model and also received the invalid geometry error. I turned on shared topology and used it along with bonded contacts and received the same error. The error may originate from the cables and I'm trying to troubleshoot that area of the assembly. Please if you can think of any other suggestions I will appreciate it.
