1 Unsafe behaviour at a level crossing
In Holland about 40% of al incidents on level
crossings with lethal consequences are related to
unsafe behaviour at a closed level crossing.• about 8 lethal incidents a year
Waiting time at a closed level crossing is an
important factor to predict unsafe behaviour.• Time between closure of level crossing and
passage of the train

1 Departure of a train at a station near a level crossing: current situation
Process:• Route setting triggers closure of the level crossing• Departure of the train is only allowed after closure
of the level crossing
Consequences:• Train waits for closure of the level crossing• Road users at closed level crossing wait for the
departure of the train

2 The idea
Parallel performance, instead of serial performance,
of the process of route setting, closure of the level
crossing and departure of the train:• Shortening total processing time• Decrease in waiting time of road users at closed
level crossing• Earlier departure of the train for higher punctuality
in train service• Use of a kind of countdown device

3 Development
Common safety method on Risk Evaluation and Assessment
Countdown on a platform • ICHRF 2015 • Melcher Zeilstra 8
3 First assessment
Several ‘interfaces’ with human behaviour:• Train staff for safe departure of the train• Train passengers / travellers for safe boarding• Road users related to level crossing safety• Track workers using a level crossing as a warning
system for arrival of a train at the working place

3 Requirements for the countdown device
• Activation of count down dependent of:o safe closure of the level crossingo safe (automatic) route setting
• Count down value related to minimum process
time for departure of a train• Departure process of a train without a pause• Actual departure of the train after published
departure time

4 Departure of train with aid of countdown
15: start of departure procedure
• First safety check of train staff
8: auditory signal to passengers
• Close all but one doors of train
• Safety check alongside train
0: activation departure light
• Close last door of the train

4 Piloting period
Piloting period: November and December 2014• With countdown• Without countdown
Reference period: June or October 2014• Without countdown
Evaluation of 6.693 train departures in total
Countdown on a platform • ICHRF 2015 • Melcher Zeilstra 12
4 Methods for evaluation
Quantitive data (all trains):• Process time for train departure• Punctuality in departure of the train• Closure times of level crossing
Qualitive data based on video images (selection):• Behaviour of train staff• Behaviour of passengers on platform• Behaviour of road users at level crossing
Countdown on a platform • ICHRF 2015 • Melcher Zeilstra 13
4 Behaviour of train staff and passengers
Behaviour at safety critical moments during train
departure procedure• Train staff:
o compliance with regulation based on risk
assessmento way of performing safety checks
• Passengers:o Possibly hazardous behaviour during closure
of doors and during departure of train

5 Behaviour of train staff and passengers

5 Behaviour of train staff and passengers
• Train staff shows safe behaviour in compliance
with dedicated regulation about use of the
countdown.• In situations with very little passengers boarding
the train, train departure procedure cannot always
be performed without a short pause.• With use of countdown passengers are more in a
hurry in boarding the train, but no dangerous
situations (train is not moving).

5 Process time for train departure
Station of Hilversum N Difference in process time for train departure
Piloting period with countdown vs reference period with countdown
828 -16.88 sec (p<0.05)
Piloting period with countdown vs piloting period without countdown
5.715 -14.88 sec (p<0.05)
Piloting period without countdown vs reference period without countdown
150 - 1.92 sec (p<0.05)
TOTAL 6.693

5 Behaviour at level crossing
About 900 level crossingclosures:Not enough data forstatistic reliable results
Predictive factor:Closure time of the level crossing with use of a countdown is 16.3 seconds less then without countdown (p<0.01).

5 Waiting time at closed level crossing
In average: 16.3 sec less waiting time (p<0.01)

6 Pay off: implementation in Holland
• Design specs are met:
> 15 sec less• No change in safety in
train departure
process• Increase in level
crossing safety• Increase in punctual
departure of the train
