V.3.e. Congestion Along Hayam Wuruk
There are several problems which are pervasive throughout the corridor but which are
more pronounced in the northern section of the corridor which are aggravating mixed
traffic congestion and slowing down bus speeds. First, buses that have continued to
operate in the mixed traffic lanes do not stop at designated bus stops, nor do they stop
only in the curb lane. They frequently consume two full lanes of traffic. The congestion
impact of this is further exacerbated as they sometimes idle in these locations waiting for
passengers. The removal of more of the bus lines with the opening of Corridor II and III
should help this problem somewhat. Tighter police enforcement of illegal stopping of
buses would also help.
There are also problems of illegally parked
vehicles along the northern part of the corridor,
as well as considerable illegal vending activity
and various forms of paratransit occupying the
roadway waiting for passengers. Much of the northern section of the corridor needs to be
revitalized, and part of an urban revitalization effort in the Glodok area should include
working out a more rational parking plan, rationalization of vending activity, and
integration of paratransit idling into the design or tighter regulation of this activity. We
estimate that two out of four lanes are lost due to these activities.
There are also several U turns in the corridor,
particularly in the northern section. The current
configuration is acceptable for locations where the
number of u-turning private vehicles is less than
1200 vehicles per hour. For between 1200 vehicles
per hour and 2000 vehicles per hour, a traffic light
separating the u-turning traffic and the busway should be used. For volumes over 2000,
an additional U-turn should be added in another location to split the turning volumes at
each U-turn. The U – turn just north of the Harmony intersection will have to be
addressed as a special case as it will have to accommodate turning buses as well.
