    Write a function that standardizes traffic signal identification codes by removing all spaces between characters, allowing for consistent pattern analysis in the traffic management system. The function should process signal codes like "GRN 123 NB" into a condensed format like "GRN123NB" to enable accurate signal timing optimization.
