Restricting car access to some suburban streets and creating bicycle-friendly promenades could improve the overall safety of cyclists on Perth roads, a workshop has been told.

More than 140 delegates, mostly representatives from bike groups and local and State governments, met yesterday to consider ways to make cycling safer at key metropolitan locations.

Among the recommendations was a new dedicated bike-pedestrian bridge alongside the Causeway and lowering car speeds on suburban streets to 30km/h.

A key focus of the discussion was the potential conflict between bikes and cars on specific suburban and arterial roads.

Consideration was given to Macrae Road in Applecross, a popular stretch for cyclists wanting to avoid busy Canning Highway.

But the road has also become a favourite morning-peak rat-run, resulting in 19 crashes involving cyclists between 2009 and 2013.

Delegates said it was important to discourage motorists from using the road and this could be done by creating dead-ends - and reducing the speed limit.

A similar speed reduction, perhaps as low as 30km/h, was recommended for the western end of Glyde Street in Mosman Park where good bike infrastructure is constrained by on-street parking, narrow pavements and roundabouts.

A plan to create a bike boulevard through Bayswater - as an alternative to the busy King William and Coode streets - was also endorsed, especially if motorists could be discouraged from using the thoroughfare.

The promenade - which would involve Leake, Lawrence, May, Edward and Catherine streets - would target younger, slower and less-confident riders.

Delegates agreed the motorists could be discouraged from using the streets with speed restrictions and traffic-calming infrastructure.

They also suggested a "meandering" centre line would prevent cars from travelling in a straight line.

The workshop was told that about 1300 cyclists shared the narrow path across the Causeway with pedestrians and other recreational users every day, often resulting in conflict.

While a dedicated bridge on the southern side of the Causeway was the perfect long-term solution, other delegates suggested a reconfiguration of the lanes to include a dedicated bike lane.

The remaining three lanes for vehicles would include a peak-hour lane so, in the morning, there would be two westbound lanes and, in the afternoon, there would be two eastbound lanes.

The workshop was held to coincide with the visit of Dutch cycling experts Arie Vijfhuizen and Martijn te Lintelo. Mr te Lintelo said it was encouraging to hear the out-of-the-box thinking of many of the delegates but it was important to remember that different areas required different solutions and there was no one answer to every challenge.

He said the use of a peak-hour lane on the Causeway would make a good "demonstration project" to gauge the public appetite for genuine and unique solutions to Perth's growing bike participation rates.

"Other demonstration projects could also look at innovative ways to link to hospitals, universities, schools and the beach," he said.
