Wanneroo Road and Joondalup Drive Interchange
The Wanneroo Road and Joondalup Drive Interchange project is funded by the Australian and State governments as part of a $2.3 billion investment in road and rail infrastructure, announced in May 2017.
Introduction Ÿ Joondalup Drive - as a signi cant east-west The project provides a future-focused solution to The project will complement other signi cant access corridor between Mitchell Freeway, the support current and projected levels of traf c upgrades in the area to reduce travel times on: Joondalup City Centre and the expanding resulting from residential and industrial development in Perth's northern corridor. Ÿ Wanneroo Road - currently used as an residential communities to the east of Wanneroo alternate route to Mitchell Freeway; and Road.

Average Delay Ÿ In 2015/16, the City of Wanneroo was the fastest-growing local government in Western Australia. By 2041, the population is KEY – LEVELS OF SERVICE (LOS) expected to grow to 400,000 from a 2016 level of 198,000 DURING MORNING PEAK

By 2029 - LOS F: Average delays of up to 110 seconds, extensive Ÿ Main Roads traf c modelling indicates that within ve years, delays and congestion service levels will deteriorate signi cantly due to increased demand. Within ten years, the intersection will reach a state of gridlock, resulting in heavy congestion, longer journey times and
increased safety risk. Delay (sec/PCU) Ave Ÿ The Cities of Wanneroo and Joondalup have also identi ed the need to address east-west traf c ow along Joondalup Drive and Burns Beach Road, which are also experiencing congestion during peak periods.
These gures refer to the performance of the intersection as a whole. Speci c legs of the intersection will fail before these dates resulting in congestion, delays and safety impacts.
[email protected] Design and con guration - Joondalup Drive over Wanneroo Road
Ÿ The concept design for the grade separation of Wanneroo Traf c count summary showing prevalence of Road and Joondalup Drive prioritises the east-west traf c east-west movement movement, with Joondalup Drive passing over Wanneroo Road. Ÿ A 24-hour video survey undertaken on 13 September 2017 (post-opening of Mitchell Freeway extension north of Burns Beach Road) showed that the through east-west volumes along Joondalup Drive were two and a half times greater than the north-south volumes along Wanneroo Road. Ÿ Based on Main Roads traf c modelling, by 2031, east-west volumes along Joondalup Drive during peak periods will remain more than twice as high as the north-south volumes along Wanneroo Road. This re ects additional traf c growth forecast on Joondalup Drive to support residential and commercial development. Ÿ The urban development catchment lies predominantly to the east of Wanneroo Road. Joondalup Drive is the major east- west route that will be used to access areas to the west including the Joondalup City Centre, the Mitchell Freeway, the train station/line and coastal area.

Ÿ Left turn access from Joondalup Drive WANNEROO ROAD (westbound) to Drovers Place will remain as present. Ÿ Drovers patrons wishing to enter the precinct J from Joondalup Drive (eastbound) can continue OON DAL to the Wanneroo Road and Joondalup Drive UP DRI roundabout, turn right and enter the precinct via VE Wanneroo Road (detour of approximately 300 metres).

Safe Systems Assessment
Pedestrians cross a single lane Ÿ Main Roads has conducted a Safe (left turn slip lane), a single traf c lane with traf c exiting Systems Assessment of the proposed the roundabout and a further con guration to ensure it meets State and two lanes entering the roundabout National road safety targets and No interaction with east-west commitments. Outcomes of the through traf c assessment con rmed: Ÿ Pedestrian exposure to traf c is reduced signi cantly as there is no interaction with east-west traf c along Joondalup Drive (more than 50% of all traf c through the intersection) Ÿ The potential severity of accidents is reduced signi cantly as the impact speed will reduce from 70km/h to 40km/h (necessitated by new roundabout).
