Title: Managing speed behaviour by defining speed limit and traffic calming strategies in CBD area :: Case study city main CBD area, Brebes Regency Indonesia
Abstract: unavailable
There are various traffic characteristics in CBD area in Brebes Regency,
shown by the mix between distance traffic, which usually with high speed, and
local traffic. This condition made the local traffic, which usually light vehicle,
motorcycle and pecidab (un-motorized), are potentially dangerous related to the
traffic accident. The local traffic authority has regulated the speed limitation on
CBD area, by stating 40 km/h for the inner CBD area and 50 km/h for the outer.
However, the traffic accident still occurs, and according to the accident data
2007-2008, the lowest zero accident probability is reaching 0.189 (Gadjah Mada
road, west-east direction), while the highest zero accident probability is only
0.453 (Sudirman road, section 2), which means that there are high probability for
traffic accident. From the speed limit violation identification shows that the
highest violation occurs in Sudirman road section 3 on 3rd peak hours (16.00-
17.00), while 91.6% vehicle breaking the speed limit. And the lowest violation
(2.3%) is occurred in Gajah Mada road, east-west direction on 1st peak hours
(07.00-08.00).
Reducing the traffic speed is the chosen method to increase the safety
and reduce speeding problems in the CBD area. These traffic calming strategies
e.g. proposing speed table, rumble strips and raised crosswalk installation,
integrated by road coloring/texturing such as “school safety zone†and other
colored pavement strategies, will be employed to reduce the traffic speed then
also to increase the safety level on the road. The indicators of changes are the
vehicle speed (85th percentile), road performance level (the changes should not
exceed the E level -
