Ottawa’s political leaders say Tuesday’s transit fiasco at the Hurdman Transitway station has taught them a few important lessons, including the difference between planning and the real world.
The problem behind the slowdown was computer modelling of traffic flow, said Coun. Stephen Blais, chairman of the transit commission.
While the modelling worked for other stations, it’s unclear why it didn’t accurately predict traffic flow at Hurdman, said Blais.
“Computer models are only so perfect. It’s difficult to predict human interpretations (of new conditions),” said Blais.
“We are trying to understand what was wrong with the (computer) model.”

Blais said eight new measures were introduced Wednesday morning to prevent the congestion that left come commuters waiting for up to an hour at Hurdman station during the Tuesday morning rush hour.
The measures included adding a special constable to a new intersection that had been equipped only with stop signs. As well, “deadhead” buses — those buses at the end of a run moving to their next run with no passengers — were directed away from the stations so they were not clogging up the station roadways.
Having the constable there to direct traffic helped almost immediately, said Blais, who noted that it took him three minutes to clear Hurdman on his Wednesday morning commute to work.
Other fixes included the opening of a temporary road and the removal of a cement barrier that made it difficult for articulated buses to make a turn.
Mayor Jim Watson agreed that “sometimes plans don’t translate well from the page to the actual implementation.”
Watson said he was angry to see all of the buses lined up Tuesday.
“I thought, ‘Why is this happening?’ We’ve put a lot of work and effort into this. No question that yesterday morning’s commute was very frustrating and we apologize for that.”
“Staff worked very quickly, along with Coun. Blais, and we found seven quick fixes that seemed to have addressed a number of the problems and my understanding is it worked much better today.”
