The research results show that headway changes with memory have significant effects on car-following behaviors and fuel consumptions and that considering headway changes with memory in designing the adaptive cruise control strategy can improve the traffic flow stability and minimize cars' fuel consumptions.
Some numerical simulations were carried out by employing the improved car-following model to explore how headway changes with memory affected each car's velocity, acceleration, headway and fuel consumptions.
This study particularly focuses on the timetable optimization problem in the transitional period (from peak to off-peak hours or vice versa) during which train headway changes and passenger travel demand varies significantly.
Because the optimal headway changes as we extend the line, we have to update the headway after every decision made.
Goodwin believes he has made headway here, changed the way people think about alternative lifestyles.
From 29 June 1924, after the takeover of Oslo Sporveier, the headway was changed to fifteen minutes.
In the tests conducted in the study, information was collected on the driver interaction with a display on the Human-Machine Interface (HMI) which provided feedback on aspects such as levels of acceleration/deceleration, lane positioning and departure warning, headway, and gear change advice.
"I was all too eager to say, 'Yes.' He had such a Notre Dame lean, I was thrilled I was making headway and might change his mind".
As it made headway, the NDP changed the landscape of Canadian politics.
And yet Greece, which has received more than 200 billion euros in bailout loans since May 2010, is still making little headway on structural changes that creditors say must happen if the economy is ever to resume growing and become self-sustaining.
