- Hi my name is Lydia and I am from GTA Consultants. I am going to give you a brief overview of the pedestrian crossing component of the King William Road Curated Street Design Project that Paul Froggatt (who you hear speak earlier) and myself worked on.
- So hopefully most of you are fairly familiar with this section of King William Road. In the main pedestrian precinct where there is a higher concentration of shops and businesses there are only two formal crossing facilities. Theres a median refuge north of Union Street and then the Mitchell/Park Street signals at the southern end of the main pedestrian area with nothing in the middle.
- So if you are a pedestrian trying to cross anywhere between these points THIS is what you are faced with crossing, unaided.
- So to work out the best locations to provide some formal crossing points to help pedestrians we got some pedestrian surveys undertaken for a full day – 8am to 6pm on a Wednesday in July. We focused on two sections in the main business precinct – one around Arthur Street and one around Boffa Street. Each of these bars represent the pedestrians in an approximately 30m section of King William Road. Around Arthur Street we counted over 300 pedestrians crossing the road, with about 100 of those using the existing median refuge (location A on the bar chart). We recorded nearly 600 crossing around Boffa Street. So there are quite a lot of pedestrians that would benefit from some crossing help.
- So this is what we decided to propose based on these pedestrian volumes and the existing crossing infrastructure. Two zebra crossings, one just south of Arthur Street and one just north of Boffa Street.
- So as these crossings are on a Council road we didn’t need DPTI approval, however we still looked at the DPTI warrant to make sure zebra crossings were going to be appropriate in these locations. The second of these two is the one we looked at meeting, looking an 8 hour average.
- In terms of vehicle warrants, King William Road carries over 13,000 vehicles per day. So we meet the average requirement of 200 vehicles per hour in our 8 hour period easily. In the peak period King William Road carries around 1,200 vehicles per hour, so it’s no wonder pedestrians might like a little help to cross the road. Council’s data also suggests that King William Road is already a slow speed environment, with mean speeds below the 30km/h operating speed for zebra crossings.
- So back to our pedestrian volumes, with A showing the pedestrians using the existing median refuge.
- These are the pedestrians we think will use a zebra crossing placed just south of Arthur Street. Pedestrians up at A would probably stay using the median refuge, and pedestrians at F might just cross uncontrolled or they might wander up to our new crossing, but it could be a little out of their desire line. So that’s 152 pedestrians recorded in 8 hours that would use the Arthur Street Zebra crossing. Of those there were 16 people who were children or elderly or disabled, which means under the DPTI warrant they get weighted as 1 and a half people. Which gives us 176. Which meets our average of 20 pedestrians an hour in an 8 hour period!
- Similarly for our southern crossing near Boffa Street
- These are the pedestrians we think will reasonably use the proposed zebra crossing as it will be close to or directly on their desire line. So that’s 424 pedestrians recorded in 8 hours that would use the Boffa Street Zebra crossing. Of those there were 33 people who were children or elderly or disabled. Which gives us a weighted total of 441. Which is well above our warrant of 20 pedestrians an hour in an 8 hour period!
- So this is the future of King William Road! An accessible street that will give pedestrians some more formal crossing opportunities to safely cross this very busy road that goes through a core local shopping precinct.
