you provide information regarding its use in this country or overseas?
AA road-speed governor has been applied
experimentally to a bus of a northern municipal undertaking, but although apparently it operated satisfactorily it has not been developed for commercial application. According to reports from America governors of this type are fitted to a substantial proportion of trunking vehicles in that country but no operational details have been released.
Many leading operators in this country would fit a road-speed governor if a suitable unit were available, and its general use could well have an influence on the choice of a power unit and transmission in a particular case.
Typically, an operator would approve a vehicle with a more powerful engine and a high top-gear ratio to reduce route times if it were not for the virtual inevitability that the driver would abuse the performance potential of the vehicle by travelling at excessive speeds on level roads and favourable gradients and thus increase wear and tear of the vehicle and fuel consumption without compensation in the form of improved utilization.
A road-speed governor could obviously provide an answer to this problem as it would obviate high-speed driving and enable a favourable vehicle performance to be exploited economically for climbing long gradients and for acceleration.
