Abstract

Safety is one of the minimum criteria that should be met on the toll road operation. Ideally, the level of safety of highway sections can be predicted even if the highway is still on the design stage. This paper aims to develop mathematical models that could be used to predict the number of accidents, by its level of severity, on inter urban toll road sections based on its average daily traffic per lane and section length. Two yearperiod of traffic and accident data were obtained from Jagorawi, Jakarta-Cikampek, Padaleunyi, and Palikanci toll road operators. Models were developed using the negative binomial regression method. The reluts show that the negative binomial regression gives desirable properties in describing the relationshipbetween the accident frequency and the average daily traffic per lane on each toll road section observed.Keywords: toll road safety, accident model, negative binomial regression.

Abstract

This paper presents the concept of a simple model to investigate the effects of land use change to accessibility. The proposed model consists of three interrelated stages submodel. The application of the model in the case of Semarang showed that residential area is most dominant zone forming the structure ofurban space, followed by the commercial and industrial zones. Related to the price of land, there is a difference in the land use and accessibility changes at 2 different time periods. Changes in the structure of space associated with an increase in land prices could affect the accessibility of the zone due to the potentialzone with high urban land price change. The concept of this model can be used as a theoretical basis for urban planners in Indonesia and is expected to be to be used as a tool to make a decision for the sustainable planning policy makers a road network in urban areas in developing countries such as Indonesia.Keywords: land use, accessibility, the structure of urban space.
