The congestion of traffic in the large city gets worse as time goes by. To solve this problem,
wide road network monitoring is required continuously.  Traffic information of main road is
gathered from vehicle detector. But traffic information about ancillary road like a highway is
rarely obtained.
Use of high resolution satellite imagery can get traffic information in road without a
vehicle detector for efficient traffic monitoring, And it makes relived traffic congestion and
broad road network monitoring be able
Then we selected the traffic information detection algorithm and applied to QuickBird
image over Seo-Myeon of 2004. Traffic information is divided three classes
This study purpose that traffic information obtained from the high resolution satellite
image is capable of monitoring traffic flow efficiently.

Within ITS project assessment, traditional cost-benefit analysis (CBA) may not fully address the  real  value  of  investment  with  regard  to  user  satisfaction,  willingness  to  pay  and  other sustainability issues. This paper examines how the Chinese  ITS  experience may be assessed through  multi-criteria  assessment  methods.  We  consider,  in  particular,  the  traffic  impact evaluation  of  Shanghai’s  highway  management  systems  and  take  the  accident  rate  of  all highways, accident economic losses, traffic volume, average speed, degree of satisfaction of the travellers, and their willingness to pay into full consideration. By an Analytical Hierarchy Process  (AHP)  approach,  this  research  evaluates  the  degree  of  importance  for  three subsystems  of  Shanghai  highway  network  to  establish  the  investment  ratio  for  each.  The funding ratio can then be used to guide investors to allocate of their funds in a scientific and reasonable way.

The freeway toll system in Taiwan may reach a new stage due to the on-going development in
electronic toll collection (ETC) system. However, in the course of testing, the high number of
regulation violation cases, the never ending appeal by regulation violators and various highly
dangerous illegal driving behavior at the time of passing through the toll collection area can
reveal the blind spot of traffic engineering planning and design for the implementation of
ETC and the way to enhance the importance of traffic safety efficiently through strengthening
of the functions of enforcement. Thus, the purpose of this paper focus on investigating the
proper system deployment alternatives based on the limitation of current toll station facilities
and its placement regulations. In addition, for future consideration when there is further
expansion of implementation,. It is hoped that through exploration and analysis of problems
and collective studies on essential issues, reference can be provided further on enforcement
strategy and establishment of a safe and highly efficient freeway ETC environment in the
future.

Traffic incidents play a significant role in the congestion on highways, causing millions of dollars
of traffic delays, damaged property, injuries and fatalities. Incident management officials are
facing challenges to reduce clearance time and minimize traffic delays, especially for serious
incidents. Traffic diversion aims to accelerate incident clearance and traffic recovery with the aid
of information dissemination technologies, policy and collaborations between stakeholder
agencies. This work assesses the effectiveness of traffic diversion at two large major
metropolitan sites in South Carolina using a microscopic traffic simulation program PARAMICS
to model serious incident scenarios and traffic diversion operations. Based on the simulation
results, this work conducted a benefit-cost analysis that suggested implementing traffic diversion strategies returned $55 for every dollar spent under prevailing conditions at the study sites.

P-Evenemang is a system of dynamic signs which are used for traffic and parking information
in the events area in Göteborg. The difference between traditional parking information
systems is that with P-Evenemang, the visitor will be guided by the event name, all the way to
the best available parking area. The P-Evenemang project has been operational since
September 2005 and was carried out in cooperation between six stakeholders, all of whom
stand to benefit, in different ways, from the system. An assessment has been made during the
period July to December 2007 to investigate to what extent expectations of the P-Evenemang
have been fulfilled.
