He has undertaken numerous research projects in New Zealand and Australia, and has peer reviewed research projects, e.g.
‘Predicting Accident Rates for Cyclists and Pedestrians’ (Beca).
He was a member of the Cycling Safety Panel, convened by the New Zealand Transport Agency to advise the New Zealand government on cycling safety, and was technical advisor to the Ministry of Economic Development for the m NZ Cycle Trail project.
Axel has developed the South Dunedin cycle network for Dunedin City Council.
The result is that approaching bicyclists have poor information about when it is safe and legal to enter the intersection.
Signal timing with bicycle-only indications should consider activating the signal with each cycle prior to implementation with detection.
If push buttons are used, they should be mounted such that bicyclists do not have to dismount to actuate the signal.
There are currently no national standards for determining the appropriate clearance intervals for bicycle signals.
Passive actuation is more convenient for bicyclists.Axel is a regular presenter at conferences and workshops, with some 70 papers and remits given.A bicycle signal is an electrically powered traffic control device that should only be used in combination with an existing conventional traffic signal or hybrid beacon.In the United States, bicycle signal heads typically use standard three-lens signal heads in green, yellow, and red lenses.An adequate clearance interval (i.e., the movement’s combined time for the yellow and all-red phases) shall be provided to ensure that bicyclists entering the intersection during the green phase have sufficient time to safely clear the intersection before conflicting movements receive a green indication.
