Paper Title
Generalized Level of Service (LOS) for Weaving Section of Conventional Roundabout

Abstract
This paper presents a development of weaving section flow model in weaving area of conventional roundabout. The outcomes were very satisfactory, indicating that the parameters considered were very crucial and relevant. Integration of weaving section capacities (QWSF and QP) enable LOS chart be developed that suit Malaysia conventional roundabout (design and operational). This being specified because of the constraint/limitation of using Arahan Teknik (Jalan) model and operational characteristics of the developed model (TISG). The main limitation of Arahan Teknik (Jalan) model in estimation capacity analysis is because it applies geometric design parameters without considering the traffic parameters such as flow and gap, and this may be considered an optimistic or ideal scenario. However, before a roundabout to be constructed, its maximum flow needs to be anticipated in order to reduce the probable traffic congestion. It can be anticipated that the Arahan Teknik (Jalan) model only can determined its capacity of weaving section based on its length of weaving section L, width of weaving section W and average entry width e. The resolution of congestion problem at weaving section is to get better estimation of flow and anticipated LOS at weaving section area under different range of traffic condition regimes such as ‘weaving section flow’ and ‘ideal safe gap’. It will produce different sensitivity of the input parameter of the calibrated models in estimating the respond parameter QWSF which is used as the measures of effectiveness in weaving area of conventional roundabout. With adequate knowledge anticipated flow and using the developed LOS the appropriate design parameters are deduced to suit the target LOS. Thus, this section has developed a ‘tool’ for practicing traffic engineer and the procedure of using it had been deliberated through stepwise example.
