Abstract
The present paper attempts to describe the commuter behavior of a sub-urban work trip through a development of a departure time choice model based on disutility minimizing approach. The model assumes that the commuters choose their departure time regarding the time attribute given the minimum value of the sum both disutility types, disutility of earliness departure time from home and disutility of lateness arrival time at the work place. In the model application, we use data from a trip characteristics survey for sub-urban commuters in Makassar, Indonesia. The result shows that the model is applicable significantly regarding the statistical assessments. Further, the commuters have threshold arrival time at work place near to the start work time. We expect that the model provides a basis in continuous further studies, such as the choice model that consider 24 hour life cycle, and a simultaneous choice model incorporating travel mode choice.

Key Words: departure time choice, disutility, sub-urban, work trips.

Abstract
This paper aims to analyze the motorcycle speed behaviors on one-directional urban roads in Makassar, Indonesia. The study conducts a survey to the speed characteristic of motorcycle on four primary roads that are one-directional type in the city. The survey was conducted on morning peak hour using video camera. Then, we extract the traffic record in calculating the motorcycle speed through replaying the video using computer in laboratory. The motorcycle speed distributions are evaluated in following the normal distribution. Parameters values of the distributions were calculated using a simulation approach. The results show that mostly the distributions follow the normal distribution. Results of F-test and t-test indicated that there are similarity and difference speed distributions, among thirty minutes interval during the morning peak period (07:00-09:00). We expect that the distribution model is useful a motorcycle traffic simulation in further studies such as motorcycle emission model, motorcycle noise model, etc.

Key Words: distribution, motorcycle, speed, one-directional urban road.

Abstract
This paper attempts to analyze the space mean speed characteristic of the light vehicle type on one-way urban roads under heterogeneous traffic behaviors in Makassar, Indonesia. The study carries out the space mean speed survey of the vehicles at four urban roads having one-way type in the city. The survey measures the speed on morning peak hour using video camera. Through extracting the recorded data, the light vehicle speed distributions are analyzed in following the normal distribution. Parameters values of the distributions have been calculated using a simulation approach. The results show that the speed distributions follow the normal distribution. The F-test and t-test results indicate that there are similarity and difference of speed distributions, among thirty minutes interval during the morning peak period. We expect that the distribution model be useful for a micro traffic simulation in further studies such as vehicle emission model, road traffic noise model, etc.

Abstract
This paper aims to understand the motorcycle ownership characteristics of households in Makassar, Indonesia. The study considers some exogenous characteristics of the households, such house types, car ownership, family size, trip number, worker number, and income. In order to analyze the relationship between those characteristics and the motorcycle ownership, we apply the multinomial logit model approach. This study carries out a survey on seven residential areas in the city. The survey based on an interviewing method using a questionnaire sheet to respondents as representative of the households, which selected randomly from the residential areas. The analysis result shows that the goodness of fit of the motorcycle ownership model is enough acceptable. Further, most of the exogenous variables significantly influence the households in motorcycle ownership. We expected that the results provide a basis for further studies such time valuation of motorcyclists, mode choice model of the households, etc.

Key Words: Motorcycle ownership, households, multinomial logit model, Makassar.

Abstract
Trip frequency on shopping travel to traditional market is one of important aspects in travel demand management (TDM) in developing countries. Regarding this, the present paper attempts to grasp the factors that significantly influenced individuals in obtaining their shopping travel frequency. The study considers socio-demography variables of households, characteristics of the shopping trip to traditional market, and travel attributes such travel time and modes. The study adopts the multinomial logit model in order to construct a causal relationship between the exogenous variables and the trip frequency. This study applies the model on the individuals that conducted shopping travel to a traditional market in Makassar, Indonesia. The analysis results showed that the house condition, family size, income, spent money, and stay time at the market are the significant variables in influencing the trip frequency. The result provides a basic insight for the further study such mode choice model for the travel.

Key Words: Trip frequency, shopping travel, traditional market.

Abstract
This paper attempts to analyze the effect of on-street parking of the school activity on the vehicle speed in an urban road. For the purpose, the study adopts the traffic macroscopic relationship models such Greenshield, Greenberg, and Underwood model approachs. Then, regarding the suitable model, we analyze effect of on-street parking volume to the traffic volume and vehicle speeds on the road. Finally, the study conducts a comparison analysis of the speed-volume relationship model between with and without parking activities. The phenomenon is observed in one way urban road locating in front of a school centre in Makassar, where the road lane is using for on-street parking. The analysis results show that the parking activity affects the traffic characteristics significantly. The activity decreases vehicle speed until fifty percent from its normal condition. The results are useful in development of traffic congestion cost model due to the activity in further studies.

Key Words: On-street parking, school activity, vehicle speed, urban road.

Abstract
This objective of this paper is to describe the current vehicle operation cost (VOC) and load factor (LF) performance of the micro-bus transit (namely, Pete-pete) which has been operating as inter-city public transport in Mamminasata Metropolitan Area (MMA) in South Sulawesi Province, Indonesia. The study focuses on the three origin-destination trips of the public transport in the area, i.e. Makassar-Maros route, Makassar-Sungguminasa route, and Makassar-Takalar route. The VOC survey for the transits uses interview method, while its analysis adopts Indonesia Ministry of Transportation. Meanwhile, the LF measurement is conducted by distance zone system as long the transit’s route. The analysis results show that three routes have similar the VOC which are categorized as highly cost. As well as, the three routes have low LF performance. The study results are useful in development of the public transport management such mode and route choice models in MMA in further studies.

Abstract
In the reformation era in Indonesia, decentralization of government regulation leads to the competition among local regency governments in developing multi-modal transportation infrastructures including container ports development. Regarding the Master Plan of Indonesia Economic Development Enhancing (MP3EI) and development plans of urban areas in South Sulawesi Province, the ports development by each local regency government needs to be managed efficiently and fully integrated. In this regard, this paper attempts to propose a holistic framework on the ports development efficiently in South Sulawesi Province, Indonesia in supporting the multi-modal transportation system. The paper adopts a supply chain approach to constructs the framework which consists of three stages, i.e. identification of influence factors the ports development and competitiveness, the ports hinterland demand analysis, and the strategies generation on the efficiency of the ports development. The framework provides a basis for some extension studies in further towards the sustainable container ports development efficiently.

Abstract
Public transportation in developing countries have been dominated by operation vehicle which has not a fix schedule for departure and arrival time, and it has not shelter or bus stop, so that it called Para transit. This characteristic has generated serious problem to urban transportation system. For the reason, the objective of this study is to analysis aspects of operations performance of Para transit vehicle that operated in Makassar city. Data collection in this study is divided into two kinds of data, i.e. the primary data that collected through a primary survey, and the secondary data that collected using a secondary survey. The analysis results show that the Para transit performances in Makassar city are unsatisfied in serving the public transport passengers within its service area. However, the length distance which is travelled by Para transit vehicle achieves optimum condition. This condition provides an opportunity in introducing a bus rapid transit (BRT) system for the city in the future.

Key Words: Public transport, Para transit, performance, Makassar.
