A new study will investigate how to make a deadly stretch of road in Brisbane's west safer for cyclists.

Main Roads Minister Mark Bailey said the study was prompted following a collision on Moggill Road earlier this year, which claimed the life of a cyclist.

"Moggill Road forms part of the Principle Cycle Network to the west of Brisbane and there have been a number of incidents along this corridor," Mr Bailey said.

"It's important that we identify potential solutions to make it safer for cyclists."
