Ibu Pejabat JKR. K. of which 711 were deaths.L Page 1 . Cawangan Jalan. The majority of these (67%) involved people crossing roads. In 1995. whereas about 33% involved people walking along (or working on) the road. there were 5286 pedestrian casualties in traffic accidents. the common use of steps instead of ramps to cater for changes in level and the common presence of deep uncovered (and often smelly) drains. to cross busy roads. Guidelines On Facilities For Pedestrians To Cross Roads It is universally accepted that pedestrians need to be provided with safe and convenient facilities. Quite recently. but in many cases these are severely obstructed by business activity. showed utilisation at some sites was less than 10 %. the excessive height of the kerbs. At many signalised intersections. These pose considerable risk to pedestrians because of the confusion between pedestrians and vehicle drivers as to who has `right of way'. Combined `Zebra' and Signalised Pedestrian Crossings. footpaths are generally provided as part of building (shop) development. Signalised Pedestrian Crossings.to be little or no enforcement of this obligation by the police. This poses a serious legal problem for road authorities such as JKR in the event of any Cawangan Jalan. These are equally confusing to pedestrians and motorists.FOR INTERNAL USE ONLY Basic Guideline on Pedestrian Facilities PROVIDING FOR PEDESTRIANS Existing Facilities For Pedestrians Crossing Roads The current facilities provided in Malaysia to assist pedestrians in crossing busy roads include: Š Š Š Š Š Pedestrian Bridges and Subways. In addition to this. There is generally poor observance of the `give -way' obligation by vehicle drivers when pedestrians enter the crossing and there appears.L court action which may arise out of an accident at such sites. The provisions for pedestrians to walk along roads varies greatly even in urban and `built-up' areas. Page 2 . most footpaths are `unfriendly' to pedestrians particularly the elderly and those who are `disabled'. while these offer a higher degree of safety for pedestrians. they are often not adopted on Federal Routes because (it is argued) it would interrupt the "free flow" of traffic on these routes. is a significant discouragement to pedestrians using the footpath and as a result even where footpaths are provided pedestrians find it more convenient to walk along the roadway. motorcycle parking and even vehicle parking. School Children's Crossings. K. street furniture. In town and city centres. A similar study of a Pedestrian Subway under Jalan SS l 64 (in the Bandar Utama area) had less than 20% utilisation. The choice of type of treatment is not always clear cut and may be influenced by economics and other factors. In respect to pedestrian bridges and subways. `Yellow and Black' Zebra crossing markings have been introduced in conjunction with traffic signals. Pedestrian (`Zebra') Crossings. The cutting of the footpath at driveways. there is considerable confusion about the obligations of vehicle drivers and pedestrians at this type of crossing. In respect to 'Zebra' type pedestrian crossings. For example a study of 10 pedestrian bridges in and around Kuantan Pahang. the lack of `ramps' at intersections and driveways. there is strong evidence that the majority of those which have been built across non-expressway routes have poor utilisation. a combination of `white and black' Zebra crossing markings have been installed in direct contradiction of the current Road Traffic Rules. Ibu Pejabat JKR. In respect to signalised pedestrian crossings. School Children's Crossings have been marked in various ways in different areas of Malaysia and none of them have any legal or regulatory backing. although at few sites utilisation was higher than 80%. rural. warrants and guides which are aimed at achieving uniformity in dealing with similar conditions and ensuring cost effective treatments. Consideration of these factors in most developed countries has resulted in a range of different types of treatments to meet the needs of pedestrians at a variety of sites and local conditions in the most cost effective way. decreases and pedestrians are delayed. With the exception of expressways. However. industrial etc. on all other classes of road will greatly enhance pedestrian safety. commercial.

Š by reducing vehicle speeds and reducing the variability of vehicle speeds. reducing traffic speed in the vicinity of a pedestrian crossing. K. In this situation the ability of pedestrians to cross can be enhanced by measures such as: Š narrowing the vehicular roadway (maintaining only just sufficient width to meet vehicu- Cawangan Jalan. The ability of pedestrians to cross roads 'atgrade' anywhere is very dependent on traffic volume (or `flow rate') and traffic speed.

At high traffic flow rates pedestrian delays can become very large and in some cases impatient pedestrians may make risky crossings in short gaps in the traffic flow. but this is assisted by the development of. which require continual `heavy' enforcement by police. and also helps to reduce traffic speed. particularly on high standard arterial roads is not easy to achieve. volume and composition of vehicular traffic. Types Of Pedestrian Crossing Facilities Pedestrian crossing facilities can be categorised into three distinct types as follows: Page 3 . This makes gap selection by pedestrians less subject to errors of judgement.FOR INTERNAL USE ONLY General Factors To Be Considered: The provision of pedestrian facilities at a particular site needs to take into account factors such as: Š the number and characteristics of pedestrians wishing to cross the road at a given location. eg urban. The imposition of unreasonably low speed limits. This shortens the distance pedestrians have to cross when exposed to traffic. the setting of realistic speed limits (even if they are higher than may be desired for pedestrian safety). is rarely if ever effective. the number of traffic lanes and is it operating two-way or oneway? Š the character of the locality. However speed control. The use of `Speed Humps' and other `vertical displacement' devices are not favoured on `arterial' roads because of the severe effect these have on heavy trucks and busses. The selection of the most appropriate treatment is often a matter of judgement. both for crossing roads and for walking along roads. Local street. The Importance Of Speed Control In respect to traffic speed. where at-grade crossings are not acceptable. this is closely related to the class of road. This situation invariably results in the occurrence of traffic accidents involving pedestrians. Š by providing pedestrian refuge islands so that pedestrians can cross the road in stages. the availability of `gaps'.L Basic Guideline on Pedestrian Facilities lar traffic capacity requirements). Questions which need to be considered are : are the pedestrians predominantly school children? age? are there disabled pedestrians who need to use the crossing? etc. Š the functional classification of the road.. is desirable as this tends to reduce the variability of vehicle speeds. vehicle conflict is necessary. at which `right of way. the number of pedestrians. however the required bridge or subway construction is very expensive and these facilities are often poorly utilised unless extensive fencing is used to deter pedestrians from walking directly across the roadway. No numeric warrants have been adopted for the provision of refuge islands and each case should be treated on its merits taking into account the volume of traffic.L Basic Guideline on Pedestrian Facilities way to pedestrians crossing the road between the flags (or flashing lights) during the periods when these devices are displayed. Grade Separated Pedestrian Crossings: Grade separated pedestrian crossings by means of pedestrian over-bridges or subways potentially offer pedestrians with the safest means of crossing busy roads. Š School Children's Crossings. to the extent that pedestrians have difficulty finding a `safe gap' in traffic (eg on a two-way road). usually provides pedestrians with an acceptable opportunity to cross a road. vehicular traffic must `give. Š The proximity to traffic signals. grade-separated crossings are essential. Controlled Crossings: At some sites with high traffic flow rates. to the degree that pedestrians have little difficulty in finding a safe gap in the traffic flow to cross the road. Where pedestrians need to cross expressway (freeway.

(preferably supervised). the speed of traffic. the above `un-controlled crossing' treatments may not provide adequate safety. In general these uncontrolled crossings are simply provided with nothing more than ramps at kerblines to bring the footpath down to explicit warrants are not necessary. Ibu Pejabat JKR. Uncontrolled Crossings: Uncontrolled crossing tend to occur by default at any location where pedestrians find it convenient to cross a road. or capacity (for heavy pedestrian demands).way' to pedestrians who are on the crossing. include the following: Š Zebra Crossings. near bus stops etc. which are the most common form of pedestrian crossing facility. `Time Separation' treatments. They should only be used on other types of roads where conditions particularly favour this solution and a high degree of utilisation can be assured. This includes `Pelican Crossing' signals and "Puffin" (Pedestrian User Friendly Intelligent") signals. K. and the provision of pedestrian phases and signal heads at conventional signalised intersections. The following are some of the factors which have been found to be associated with low utilisation of pedestrian bridges or underpasses: Š Low traffic flows. at which by statutory regulation. either supervised or not supervised. the provision of a pedestrian refuge island may be justified. the type of pedestrians (eg children.

Most of the `well proven' techniques and devices are currently being used in Malaysia. it is suggested that those presented in the AUSTROADS (Australia) Guide To Traffic Engineering Practice.Pedestrians. The desirable general layout etc for various types of pedestrian crossing facilities are illustrated in Figures 2 to 7.5m (for low pedestrian flows) to 4 m (for high pedestrian flows). and in view of the vulnerability of pedestrians in any conflict with vehicles (including motorcycles) some form of segregation is desirable. Provisions For Pedestrians At Signalised Intersections At intersections where traffic signals are installed to control conflicting traffic movements. Warrants And Layout Guidelines Consideration of the various factors relevant to the choice of the appropriate type of pedestrian crossing leads to the presentation of a range of different types of facilities to suit various classes of road and different road environment situations. there will usually be sufficient pedestrian movements to justify the provision of pedestrian facilities. Guidelines For Providing Facilities For Pedestrians To walk Along Roads: There are few places on the road system where no provision needs to be made for pedestrians to walk along a road. are long and not well lighted. These are attached as Appendix A of this report. particularly for women. conventional signalised pedestrian crossings as illustrated in Figure 5. except where this traffic movement is proceeding on a green arrow signal. The pedestrian phases at signalised intersections are usually incorporated into the signal cycle in parallel with non-conflicting. At signalised intersections with significant pedestrian movements. In the absence of quantitative and other guidelines specifically developed for Malaysian conditions. Note that Zebra type markings must not be placed across the main carriageways at signalised intersections. (derived from Australian Standard AS 1742. Ibu Pejabat JKR. traffic signing and roadmarking vary greatly from site to site. It is generally accepted that conflicts between left turning traffic is acceptable except where high speed `slip' road with 2 or more traffic lanes are provided. 10). the provision of special signal heads Cawangan Jalan. Š The provision of steps (stairs) rather than ramps at pedestrian grade separations has been found to be a discouragement to pedestrians. personal security can be a perceived problem. at important intersections within cities and towns. Guidelines for the selection of the most appropriate type of treatment are provided in Figure 1. not withstanding this. However where the intensity of Page 5 . It is also generally acceptable to allow the conflict between right turn vehicular traffic and pedestrians crossing the roadway into which the right turners are entering. The type of pavement marking to be used to indicate the pedestrian crossing at signalised intersections is similar to that used at signalised pedestrian crossings away from intersections ie. or the least conflicting traffic movements. be adopted as `Interim Guidelines' until such time as experience in practice indicates any necessary changes to better suit Malaysian conditions. but the main problem is that particular treatments are often used at inappropriate locations and the geometric design. K.L Basic Guideline on Pedestrian Facilities (faces) and signal phases to assist pedestrians to cross safely can be incorporated at little additional cost. These consist of white transverse lines marked across the carriageway the width between which may vary from a minimum of 2. `Zebra' type pedestrian crossings may be installed across any separate left turn `slip' road.FOR INTERNAL USE ONLY sation of any grade separated pedestrian crossing facility. children and elderly people. In general. some guidelines / warrants for such provisions are included in Appendix A. Š Where subways are depressed below ground level. Such facilities often experience poor utilisation even in daytime. but never in conjunction with a signalised left turn `slip' road. Part 13 . 0 m should be provided between the traffic lanes and the footpath. While no numeric warrants are given for the provision of footpaths along roads. Where footpaths are provided. In some countries these are referred to as "Shared Zones". Cawangan Jalan.4 m or wider in shopping and other high pedestrian activity areas. This clearance. gradients of 1 in 20 to 1 in 33 should be provided. or unreasonably obstructed by motorcycles and bicycles. or speed are high. Š A height clearance of at least 2.9 m to 2. In some city and town situations. Ibu Pejabat JKR. the kerb should be `dropped' and a ramp at an acceptable slope should be provided.L Š Changes in level along and beside the foot path should be minimised. Where the footpath crosses or intersects the kerb as at intersections and drive ways. This pedestrian priority is greatly enhanced if vehicular traffic is ramped up to footpath level. In general driveways should not `cut' the footpath but should be ramped up or down from roadway level to meet the footpath level. which could pose a danger to pedestrians. Where kerbs are provided at the edge of the carriageway. poles. consideration should always be given to the needs of elderly people and people with disabilities. Š Footpath surfaces should be firm. Where long ramps are involved. should be covered. the road shoulder can adequately provide space for people to walk clear of vehicular traffic.

K. where there may be very high pedestrian activity. In addition. smooth and skid resistant. if they cannot be avoided. should be kept flush with the footpath surface and any drains close to the footpath. The need for pedestrians to step down to the driveway level and back up to footpath level at each driveway is a major discouragement to pedestrians using the footpath. such as at pedestrian bridges. even. they are generally considered necessary in all "built-up" areas and may also be necessary at some rural locations such as in the vicinity of schools. pedestrians should be given `right of way' (priority) over vehicular traffic where drive ways cross the footpath. to reduce the degree of threat to pedestrians posed by vehicular traffic. These situations in which vehicles and pedestrians share the road carriageway require specific traffic rules which give pedestrians equal priority to vehicles together with special traffic management arrangements. Š The pathway should not be obstructed by posts. mosques or other community facilities where pedestrians are likely to be concentrated. Where differences in level are catered for by a ramp instead of or in addition to steps. especially by people with impaired vision. on 'local street' class of roads. including a maximum speed limit of 25 km/h or less. which should be greater where traffic volume and. is amply emphasised by the high number of traffic accident casualties involving pedestrians.FOR INTERNAL USE ONLY conditions.
