The accuracy of measured traffic flow on a roadway largely depends on the correctness of the PCU factors used for converting traffic counts. PCU is the number of passenger cars that are displaced by a single heavy vehicle of a particular type under prevailing roadway, traffic and control conditions. The aim of the present study is to develop more appropriate models for estimating the equivalency units of different vehicle types on multilane highways, considering the limitations of available methods. Estimation of equivalency units for vehicle types is described by developing speed models based on multiple non-linear regression approaches. The equivalency units estimated by using models are found to be realistic and logical under heterogeneous traffic flow conditions. The PCU values estimated by the multiple non-linear regression method are compared with and found to be relatively higher values than the values obtained by the dynamic PCU. The accuracy of the models is checked by comparing the observed values of speed with estimated speeds. The multiple non-linear regression approach is also used for estimating the equivalency units on six-lane divided highways. Results indicate that the proposed methodology can be used for estimation of equivalency units for vehicle types under mixed traffic conditions.

ABSTRACT
This thesis discusses the results of research on the effectiveness of theimplementation of Dikmas Lantas against compliance of traffic of high schoolstudents SMU in Bogor City Police Law Area. This research conducted done byobservation, interview and documentation method. The results showed Variousforms of traffic violations by high school students in the Bogor City Police area are not wearing helmets, red lights, no SIM vehicle registration, not turning on lightsduring the day and riding more than two people. Nevertheless, the results ofinterviews with some students found that there were factors that caused theviolations committed by the students, namely the encouragement of parents and theabsence of prohibitions provided by the school when bringing their own vehicles toschool 2 Some forms of Dikmas Lantas activities conducted by Satlantas PolrestaBogor Kota in various high schools in Bogor City Police area, such as PolisiSahabat Anak, Police Goes to School, Safety Riding Traffic Park, SakaBhayangkara Scout and Safe Way to School 3 Implementation Dikmas Lantasthen conducted by Satlantas Polresta Bogor City in various high schools in LegalPolice Bogor City running effectively, which is marked by several indicators,including a trend of decreasing the number of traffic accidents that occurred at theage of students in the jurisdiction Polresta Bogor City from 2015 to 2017 by 55percent.
