    abstract = {Congestion is a major problem of transport activities in big cities including in Indonesia. There are
a lot of factors have caused congestion, there are indiscipline of road user, weak law enforcement and the
increase of two-wheeled vehicles. The objectives of this study are to analyze change in travel time values,
efficiency of vehicle operating costs and carbon dioxide emission efficiency with applied geometric widening
intersection in Makassar. This study was performed at Makassar City, South Sulawesi. The sampling technique
in this study was accidental sampling and direct field observation of vehicle at the intersection. The study sites
were 4 arm of intersection In Makassar as follows Veteran Utara (VU) Street Veteran Selatan (VS) Street Sungai
Saddang (SS) Street and Sungai Saddang Baru (SSB) Street. Data of vehicle volume from 4 arms were used to
estimate the projected situation from 2015-2025, consisted of speed, capacity, delay and level of services. Data
of vehicle operating cost was analyzed using assumptions of income approach. This study showed that travel
time values were highest on Class 2A vehicle and lowest on Class IIB vehicle. Projection data showed that in
2025 the travel time values were triple. Overall, VOC efficiency in all arms was lowest in Class 2A while the
highest was in Class 1. In the analysis intersection improvement through geometric design may increase vehicle
speed and thus more benefit in VOC in order to accelerate the movement of goods and people.}
