Syazwani Sahrir, Syahriah Bachok & Mariana Mohd. OsmanThe Effectiveness of Provision of New Static Information Signage: A Case Study of IIUM, GombakMaintenanceMaintenance is a straightforward undertaking that requires no formal training orspecial skills. The cleaning and repainting of signs is of the utmost importancein order to stimulate the concentration of the driver and satisfactory of thefunctions (Hobbs, 1979).Siting of signsOther measure of effectiveness is the siting of traffic signs. The correct siting ofthe traffic sign from the hazard is also vital in relation to vehicle speeds.Locating a sign too close to a hazard is unlikely to give drivers sufficientwarning and message (Hobbs, 1979).IlluminationThe application of lighting or illumination is the deliberation of light to achievesome aesthetic or practical effect. Lighting includes use of both artificial lightsources such as lamps and natural illumination of interiors from daylight(Matson, Smith and Hurd, 1955). Practically all traffic signs use retro reflectivesheeting. Retro reflective sheeting is designed to return light from theheadlamps with just sufficient spread of beam to include the driver’s eyes(Matson, Smith and Hurd, 1955).GUIDELINES IMPLEMENTATION FOR TRAFFIC SIGNSThe authority of Department of Public Works (JKR) (2006), Malaysia has comeout with crelevant guidelines that need to be observed in providing the trafficsigns. The purpose of these guidelines is to establish uniformity in design andapplication of all traffic signs and control devices in Malaysia for the benefit ofroad users, road and traffic authorities, and manufacturers of traffic signs. Thestandardisation is very important in order for the road users to experience andbe familiar with the traffic signs. The uniformity in design encompasses theshape, word messages, symbols, size, colour, illumination or reflectorization(Manual of Traffic Control Devices JKR, 2006).© 2012 by MIP 88
PLANNING MALAYSIAJournal of the Malaysia Institute of Planners (2012)Guidelines for Informatory signsThe informatory signs are provided for the convenience of road users as well asfor improving the efficiency and safety for roadway. There are fourclassifications of informatory signs which are (1) destination signs, (2) distanceSigns, (3) information signs and (4) route markers (Manual of Traffic ControlDevices JKR, 2006). This study will be focusing more on the informatory sign.i. Colours and Shapes of Guide SignsBasically, the informatory signs are rectangular in shape and the colourgenerally either white letters or symbol and border on blue background.However, for local streets, the letterings and arrows should be yellow incolour.ii.iii.Size of Guide SignsThe size of informatory signs must be legible to road users and followthe standard size. However, for other guide signs, the legend is sovaried that the size must be fixed in terms of the length of wordmessages and the size of lettering and spacing necessary for properlegibility are ensured.Lettering On Guide SignsThe lettering for the informatory sign should be clear, open capitalletters of the type approved. The names of places and rivers should bein lower-case lettering with initial capitals.CASE STUDY OF STATIC INFORMATION SYSTEMSeveral criteria like conspicuity, legibility, distinctiveness, and comprehensionmust be met for a sign to be effective. There are five cognitive features are ofcentral concern in sign research (Ng and Chan, 2008). They are familiarity,concreteness, complexity, meaningfulness, and semantic distance. Ng and Chan(2008) employed a 0 to 100 points scale for rating cognitive features.Familiarity is defined in terms of the frequency with which icons had beenencountered. For a group of novice subjects, significant and positiverelationships were found amongst the cognitive features of familiarity,concreteness, meaningfulness and semantic closeness (Ng and Chan, 2008).Furthermore, the study by Schnell (2010) investigated the effect ofluminance and letter size on the information acquisition time and transfer89© 2012 by MIP
