In heterogeneous traffic analysis, traffic flow is measured by converting the values of different vehicle types using Passenger Car Equivalents (PCE) values. School Safety lone (ZOSS) facilities were provided by Indonesian Government to improve the safety of pedestrian by controlling the speed of vehicles near primary schools located around the main road. The effect of school locations around the main street is the presence of roadside activities such as pedestrians, private vehicles stopped, and bus stops. This condition will affect the traffic flow. The objectives of this research were to develop the model of PCE values for Indonesian urban roads equipped with ZOSS, and to determine how much the lOSS changes the PCE values. The surveys were conducted in 9 roads, in Surakarta, Sragen, and Y ogyakarta. Each road was divided into 4 loci corresponding to the locations of camcorder, i.e. Locus B (before), Locus l (at zebra crossing), Locus A (after) and Locus 0 (outsideZOSS area). Road segment was used to see the changes that might occur in 9 different locations, while locus was used on the same road but at certain point were equipped with a relevant facility of lOSS. This research has used the speed ratio method which expressed the ratio between the average speed of a vehicle type and the average speed of cars. This variable was combined with the percentage and a dimension ratio of each vehicle type, as well as with a measure of side friction. The recommended model was modified based on the Speed-Based Method referring to the Indonesian Highway Capacity Manual.
