Traffic movements in the city of Jakarta is linked to the Jakarta Outer Ring Road (JORR) Toll Road. This road network has a high traffic volume because it is integrated with other toll roads that connect between an other cities of Jakarta. The condition of roads heavy traffic volume in the event of road rehabilitations will cause travel obstacles starting from increasing travel time to the long delay in traffic flow at the window time. The travel delay caused losses to road users. Road management must make attention to the impact of the zone rehabilitation to losses time by road users, especially on toll roads. This study analysis the impact of changes in speed in the work zone with short, medium and long work areas. From these 3 types, it can be seen the costs by road users due to the travel time. Traffic surveys have been carried out on the Jakarta Outer Ring Road Toll Road (JORR) section S using the roadpod metrocount tool. This tool can calculate the decrease in speed along with the volume of traffic in the three locations of the work zone. Loss of road users due to travel delay is calculated from vehicle operating costs. The results of this study are known to increase vehicle operation costs by 20% to 40% due to a decrease in speed caused by work zone. The results of this study are expected to be make consideration of road operators in determining the time in choosing of rehabilitation by minimizing the losses of time from the road users.
