Nearly six times the number of employees, but only about four times of passenger cars, because of better residential properties and transportation like free shuttle bus and train stations around Tainan Park.
On Friday passenger cars from Tainan Park were even more than morning, seems that some employees stay around Tainan Park on weekdays and return home on weekends.
Same
Every Friday will be early to get off work, other than weekdays, Monday to Thursday are between about 17:00 to 20:00.
Space
Include Highway No.1 No.3 No.5, not include the province road, county road or general road.
Human Factors
Some vehicles don’t have the ETC identification stickers so that we can’t know their origin and destination.
The use rate of ETC and the number of users over the
years are different. It may cause research errors when they are compared.
DISCUSSION
DISCUSSION
CONCLUSION
Influence Range of Southern Science Park
Both Tainan and Kaohsiung science parks had the greatest volume from old Tainan City, but Tainan park had farther influence range than Kaohsiung park although it’s not a decreasing form.
Influence range may depend on employees, surrounding environment and development time of science parks.
CONCLUSION SUGESTION
Provide a reference for Taiwanese construction sites in the future.
More persuasive through the real data and establish a set of ETC data analysis process.
Build a database of influence range of important constructions and visualize them as the basis for long-term observation.
CONTRIBUTION
Add buses and trucks of the situation and complete the influence range of other science parks with comparative analysis.
Add other kinds of construction such as tourist spot and transport,
recreation areas, airports and ports to improve the influence range of the database.
Data Limitation
In the future it may use VD data for comparison.
The VD data provided by MOTC include the traffic flow from east to west freeway and provincial road, but it does not include the direction.
