השוואת תנאי עבודת עתקים ודרישות בטיחות נעשתה בהתאם לדו"ח מבקר 3/13. Improving Safety at Level Crossings Udi Kaplansky (MSc. Safety Engineering) VP Safety, Security, Environment and Standards

BACKGROUND 2 major train accidents occurred during 2005 and 2006. Casualties – first time people killed and injured inside train. Outcome – Major organizational & conceptual changes initiated: Safety management. At ISR level. At government level – MOT, MOF.
10
BACKGROUND Understanding of the potential – Acceptance of the possibility. Understanding of the risk – beginning of risk assessment. Definition of 2 levels of risk: Risk for the train – Passenger or Freight (Hazard Material). Risk for other – trespassers, car occupants, workers, passenger at a station, damage only...
11
BACKGROUND Understanding of the risk – beginning of risk assessment 3 major scenarios: Derailment Train Collision Train – Car (Truck) Collision – at level crossing. HIGHER PROBABILITY
12
2 Main Courses of Action Grade Separation Level Crossing maintenance & improvement
13
Safety Actions Taken Nomination of Railways Regulator function within the Ministry of Transportation. Allocation of resources – a long term multi-year plan (MOT, MOF). Government Level Promotion of statutory planning for Grade Separations - MOIA. Setting a plan for grade separation (MOT).
14
55 Grade Separations were built (of 154 existing LC on 2006). 34 of them were built by ISR. GRADE SEPARATION
15
LEVEL CROSSING Remaining LC - 76: 57 on main lines (passenger & freight) including 7 pedestrian LC + 4 closed with gates. 11 on sidings – only freight lines, limited speed (max 60 km/h), barriers. 8 on industrial plants – only freight lines, limited speed.
16
LEVEL CROSSING
17
Establishment of Level Crossings & Grade Separation Administrative Committee, (Inter-ministerial) managed by the General Manager of MOT. Defining a Ranking Model for LC based on risk level assessment and budget. Government Level Setting a plan for grade separation (ISR, MOT, MOF). Update instructions for level crossing planning. Law Enforcement. Level Crossings - Safety Activity - How much safety can be achieved per €.
18
Establishment of Safety Division (2006) – division director at a VP level. Establishment of Road & Traffic Arrangement department as part of the Safety Division. A British consulting firm for railways safety was hired to independently analyze ISR safety status. Definition of Safety Plan - necessary steps to be taken by ISR. ISR Level Level Crossings - Safety Activity
19
ISR Level Defining steps to be taken to reduce Level Crossing Hazards and setting : Level Crossings - Safety Activity Definition of a Minimum set of actions and devices to be implemented at LC according to characteristics – a threshold Standard LC “Suit”. A Plan for implementation at all LC according to Risk Rank. 1 st Step - all Level Crossings on passenger lines were protected with barriers, flashing lights, bells and traffic signs. All barriers are SIL4. Prevention by technological and non-technological means.
20
Based on the LC Safety Survey – 2 groups of focus: Level Crossings - Safety Activity Car Drivers approaching LC – preventing the car driver from accessing the LC by means of precursory warning devices. Train – alerting the train driver of a danger to the train by means of obstacle detection devices. ISR Level
21
PRECURSORY WARNING DEVICES
22
Precursory Warning Active Signs for Vehicle Driver In cases when there are visibility limits (limited FOV) for vehicle drivers approaching crossing, such as a curve or vegetation blocking view, there is a need to precursory alert of vehicle driver, especially when the barrier is already activated. The system consists of a permanent traffic sign integrated with flashing lights. When the train is approaching a pulse from the train signaling system activates the flashing lights.
23
23 Precursory Warning Active Signs for Vehicle Driver When flashing a train is arriving – slow down for stopping

24 Precursory Warning Active Signs for Vehicle Driver
25
Vehicle queue-prevention using Precursory Traffic Lights The profound examination of different kinds of accidents on level crossings identifies a lot of vehicle queue events, because of the traffic jam downstream. In order to prevent cars gathering on the level crossing it was suggested to install the Precursory traffic signal about 24 meters before the barrier.
26
The system consists of traffic lights, controller, and queue detector downstream. The controller receives continuous pulse from train signaling system when barrier is activated. The light switches to red when: Train approaches X seconds of continuous occupation of queue detector Vehicle queue-prevention using Precursory Traffic Lights (X is preset according to LC characteristics)

Loop Detection and Warning System
36
Add this system to all main line LC as part of the Basic Protection “Suit” in addition to barrier, flashing lights, bells and traffic signs. The logic - to implement a reliable relatively cheap (therefore can be widely installed) obstacle detection system at all LC (actively or passively protected), as part of the basic standard suit instead of limited installation of well known extremely expensive devices (such as radar scan or video motion detection camera).

Loop Detectors System Loop detector system solution was selected because: Proven all weather reliability Sensor - familiar and commonly used device Quick and low-cost installation Simple and low-cost maintenance Not susceptible to vandalism
42
Loop Detection and Warning System is implemented at 63 LC. This include all main lines - passenger and freight. Loop Detection and Warning System
43
Implementing safety improvements at LC – general repairs, asphalt, repainting of signs, lightning, signaling etc. Conducting a routine of repeating surveys and continuous maintenance of all LC several times a year. Synchronizing LC Precursory Traffic Lights with junction traffic lights (when close). All LC are periodically supervised by MOT Regulator. ISR Level Level Crossings - Safety Activity Conducting a routine of LC risk assessment each month checking the status of all LC, trend and precursors.

How do we know that it’s working? Yearly Barrier Braking by Car
