A few days later, five people were killed at a rural intersection that would have been a candidate for treatment. It was then rejected by the Department of Transport and Planning. I recently submitted a detailed proposal to the Transport Accident Commission for a statewide program of low-cost treatments to remove hidden safety traps at rural and urban intersections. Sweden incurred the same problem when it amalgamated road and transport departments: road safety got lost. Mind you, there’s no one left to talk to since her government got rid of the last vestiges of expertise at VicRoads, then abolished VicRoads into the Department of Transport, then downsized what was left into the Department of Transport and Planning. She must be talking with the wrong people. The road safety minister says it’s “behaviours that people are taking out onto the roads that are causing these fatalities and these collisions”, with the overly simplistic implication that education and enforcement are the solution. This focus on speed diverts attention from the detective work that’s needed to prevent serious crashes. The Safe System, with its aim of zero fatal and serious injuries, is not the solution to our road safety problems – it is the problem. In late 2015, Victoria adopted the Towards Zero strategy. Isn’t it ironic that we have seen more speed limit reductions over the past decade than ever before, yet the the number of fatal and serious injuries goes up, not down. The Age joins this parade of the well-meaning with its editorial on June 21, pointing to lower speed limits (“ We can do more to save lives on our roads”), the great road safety cure-all of our time. Road safetyĮveryone’s a road safety expert, offering simplistic solutions to a complex problem.

We could just call it a function, but often in optimization problems multiple functions come in to play, including functions that add constraints to the problem, in addition to the function we're optimizing
Linear programming is, simply put, an optimization problem in which the objective function and constraints are all linear.
