Some limitations today are: – Headways are sometimes too small – Unnecessary stops for meetings are not eliminated – Priorities between trains are not specified – The interactive connection to human control is not developed – The integration of the PMM into the HMI of the traffic controller is not developed FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 13 A delayed Scenario 1 - ROMA iron ore train FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 14 Short Scenario 1 - ROMA headways FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 15 Unnecessary Scenario 1 - ROMA stops not eliminated FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 16 Priorities Scenario 1 - ROMA between trains ?
