Engineering (Signalling) StandardESD-03-01 Level Crossing DesignLevel Crossings: Definitions, Types and Classifications1Level Crossings: Definitions, Types andClassifications1.1IntroductionAll road/rail intersections (grade or level crossings) are provided with either passive or activeprotection. Passive protection is the application of passive traffic control devices (signage) whichprovides an unchanging warning to the road user whether or not a train is approaching thecrossing.Active protection is the application of warning devices to warn road users of the approach of atrain when the train is a minimum time from entering the road-rail intersection. In some casesit also blocks access to the crossing.This section addresses the terms and definitions relating to those locations where active levelcrossing warning or protection devices have been provided for the safety of road users,pedestrians, and rail traffic.The terms and definitions used throughout this standard are generally aligned with the wordingused in the current Australian Standards and other Rail Authority Documentation.The arrangements proposed for each level crossing shall be approved by the Road Authority,Local Government, ARTC, other Rail Authorities involved and any other Local TrafficManagement Authority before a detailed design can be commenced. The Project Manager for thework shall be responsible for producing a project scope for signature by the necessary parties toensure that they are in agreement with the proposed level crossing arrangement.1.2Protected Level Crossing (Public or Private Road)A Protected Level Crossing is defined to be a road-rail intersection at which a risk assessmenthas determined that the hazard is such that provision of active warning and/or protectiondevices is required in the interests of the safety of the road traffic, pedestrians and rail traffic.Active warning devices are provide for the protection of crossing users and there are no passivetraffic control devices such as “GIVE WAY” or “STOP” signsTypes of Active Level Crossing ProtectionThese are defined in this standard as Level Crossing controlled by Flashing Lights. Level Crossing controlled by Flashing Lights and Half-Boom Gates. Level Crossing controlled by Flashing Lights and Four Quadrant Half-Boom Gates.In this Standard the term Half-Boom Gate shall be synonymous with the terms Boom Barrier orBoom Gate. Four quadrant gates shall refer to application of half boom barriers arranged tocontrol entry to and exit from the road-rail intersection.AS1742.7 defines the signage, marking and road layout applicable to each type of crossing.1.3Protected Pedestrian Level CrossingA Protected Pedestrian Crossing is defined to be a pedestrian-rail intersection at which a riskassessment has determined that the hazard is such that provision of active warning and/orprotection devices is required in the interests of the safety of pedestrians.Types of Pedestrian Level Crossing ProtectionThese are defined as:Version 1.3 Pedestrian level crossing controlled by lights. Pedestrian level crossing controlled by lights and boom barriers or swing gates.Date of last revision: 22 Nov 12This document is uncontrolled when printed.

Engineering (Signalling) StandardESD-03-01 Level Crossing Design1.4Level Crossings: Definitions, Types and ClassificationsLevel Crossing Warning SignsA level crossing warning sign is a warning sign provided to advise road users of the location of aroad-rail intersection as defined in AS 1742.1.5Level Crossing Passive Traffic Control DevicesA regulatory sign, as defined in AS 1742, provided to require compliance to a Road traffic lawwhich defines road user actions required when crossing a road-rail intersection.1.6Types of Level Crossing SignsAll level crossing signs, both at and approaching the level crossing, shall be in accordance withAustralian Standard 1742.7 except that in specific situations, supplementary signage may beadded to define a particular function or requirement.1.7Warning LightsThe assembly for a protected public level crossing shall be the RX-5 flashing light assemblydefined in AS 1742.7.Where the usage and type of road traffic justifies private level crossings may also be fitted withthe RX5 assembly,In this standard the term RX-5 shall be synonymous with the term Type F Highway signal.All new/upgraded installations shall use the R6-25 sign as part of the RX-5 assembly, exceptwhere wind loading (in the case of gantries, for example) precludes the use of the R6-25 sign.1.8Advance Warning LightsTwo side by side yellow flashing lights mounted on the same post as the W7-4B (or C) roadsign, generally within a sign reading “Prepare to Stop” as defined in AS 1742.7. Used where theroad layout, approach speed, sun glare or obstructions limit the motorist’s view of the Type Fsignals at the level crossing or there are other risk factors identified. Advance warning lights canbe provided on all types of road level crossings.1.9Supplementary Warning LightsSteady red lights fitted as a supplement to the passive traffic control signs “STOP” or “GIVEWAY”, generally at private level crossings, where limited sighting of approaching trainssignificantly increases the risk to road users and trains.Supplementary warning lights may also have application to minor secondary unsealed publicroads as agreed between the rail and local road authorities.1.10Level Crossing ControlsCrossing Controls are defined to be the electrical (or electronic) controls necessary to initiate,maintain and end the operation of the warning and protection devices at a level crossing.The Crossing Controls may be initiated automatically or manually or by a combination of both.The Crossing Controls may have to be interlocked with railway signalling equipment controllingthe passage of trains over the level crossing and depending on the complexity of thearrangements a number of “special controls” may be required.At some locations it may be necessary to integrate the crossing controls with other systems, forexample those controlling highway traffic lights.Version 1.3Date of last revision: 22 Nov 12This document is uncontrolled when printed.

Engineering (Signalling) StandardESD-03-01 Level Crossing Design1.11Level Crossings: Definitions, Types and ClassificationsLevel Crossing OperationOperation is defined to be the sequence and mode in which the Crossing Controls operateincluding the manner in which the level crossing warning and protection devices operate.The mode of operation for all types of level crossing arrangements shall generally be inaccordance with the AREMA C&S Manual and AS 1742.71.12Level Crossing Warning TimeThe level crossing warning time is defined as the minimum time of operation of the warningequipment for the fastest train from the initiation of the warning sequence until the front of thetrain reaches the road-rail intersection.1.13Approach sectionThis is the section of track which when occupied by an approaching train will cause the levelcrossing warning equipment to operate.1.14Holding sectionThere may be two trains approaching a level crossing. It is required to have a minimum timewhen the boom gates have lifted before they operate for the second train. A Holding track isused to extend the approach activation for the second train to include this additional time.1.15Tail FlashingThis is when the level crossing continues t

implemented a crossing guard pilot that transferred responsibility for crossing guards from the Richmond Police Department to the Richmond Public Schools (RPS). With the same level of funding, RPS was able to expand the crossing guard program from seven crossing guards at seven schools to 36 crossing guards at 12 schools.
California School Crossing Guard Field Assessment Tool Assessment Areas: 1. The Crossing Guard is wearing the appropriate uniform authorized by the Crossing Guard Local Program. 2. The Crossing Guard is utilizing the proper equipment (e.g., retroreflective vest, STOP paddle, whistle, gloves) as authorized by the Crossing Guard Local Program. 3.
County Police Academy have adopted the crossing guard training program developed by VTC for instructing some crossing guards in their regions. To learn more about the training's effectiveness, VTC led crossing guard training in September 2014 in Middletown Township (73 crossing guards) and the City of Newark (122 crossing guards).

additif a en fait des effets secondaires nocifs pour notre santé. De plus, ce n’est pas parce qu’un additif est d’origine naturelle qu’il est forcément sans danger. Car si l’on prend l’exemple d’un champignon ou d’une plante toxique pour l’homme, bien qu’ils soient naturels, ils ne sont pas sans effets secondaires.
