Downtown Houston’s light rail line is experiencing delays caused by a change in traffic signal priority, reports Jay R. Jordan in Axios.

As Jordan explains, “Since the system was launched in 2004, most of Metro's on-street light rail trains have benefited from traffic signal preemption — to keep trains on schedule and encourage ridership.” Now, changes made in late September are forcing trains to stop at red lights and wait for the full cycle. 

“In a statement to Axios, Metro said the changes were made in conjunction with Houston Public Works to ‘enhance overall mobility’ for drivers, bus riders and pedestrians.” However, the changes are lengthening commute times for light rail passengers. 

According to Jordan, “The changes come as Mayor John Whitmire has reversed some transportation policies of his predecessor, Sylvester Turner, who sought to create better options for people who don't have access to a car to get around town.”
