Automated section speed control is a fairly new traffic safety measure that is increasingly applied to enforce speed limits. The advantage of this enforcement system is the registration of the average speed at an entire section, which would lead to high speed limit compliances and subsequently to a reduction in the vehicle speed variability, increased headway, more homogenised traffic flow and increased traffic capacity. However, the number of ...

Speeding is an important risk factor in road safety and police activities with regard to traffic (safety) are therefore to a large extent focused on tackling this problem. Within this study, researchers from Hasselt University worked together with 3 regional police units to test the effect of two frequently used speed interventions namely a speed control (i.e. stationary police control in an unmarked police car equipped with a mobile radar) with ...

This paper proposes a new closed loop speed control of induction motor fed by a high performance Z-source inverter (ZSI), the speed control is based on V/F and indirect field-oriented control strategies (IFOC). The indirect field-oriented control based on PWM voltage modulation with voltage decoupling compensation is used to insert the shoot-through state within the switching signals. A dual loop controller is designed to control the peak dc ...
