An overview of urban traffic Information system with the accelerated process of urban modernization, urban transport systems in the fields and increasingly wide range of traditional traffic management appeared to be inadequate, the introduction of urban traffic Information system to improve urban traffic management as an important way. Information system designed to relieve urban traffic congestion that the traffic pressure on traffic in the city-wide distribution become more reasonable, to reduce or eliminate the impact of road bottlenecks, improve road capacity and service levels.

Urban road traffic information system including the functions front: the driver club, latest news, real-time traffic information, the latest announcement, travel path query, the query road conditions, illegal exposure, the Secretary-mail, text messaging platform, safety knowledge, by Case, illegal information, traffic management features such as forums. background includes: information on the Forum's audit, the audit SMS platform, the latest notice issued, the audit information for administrators, database backup and other functions. For the majority of people travel brings great convenience, saving on the road waiting time and improve work efficiency.


2ABCUpload concept
ABCUpload is to allow users to move files from a web browser to upload to the user's IIS web server ActiveX control, which does not require any client software installation through a standard multipArt HTML forms to implement server-side operations.

ABCUpload features the following points.

(1) allows the site users do not need any client software, you can view their real-time upload progress (2) comply with the Unicode standard, such as Japanese and Korean can support any language, etc. (3) to work with MacBinary compatible, able to Macintosh, Windows and UNIX systems use the browser. (4) ABCUpload Form object is based on Microsoft Form object, to be able to maintain the existing code with the user's maximum compatibility (5) to support binary (BLOB) objects, so users can upload files directly into the appropriate database.


3ABCUpload application results in this system because each road and each intersection has a detailed description on an Excel table, this table should go into a server so that staff can access.

First, to create a "ABCUpload4.XForm" object theForm, then get to the concrete by the Figure 1 the path on the theField, also set up a table of storing Excel file name and path ".. / excel", then the timestamp technology with strDiff value as the name of the excel sheet, that is now past a certain time minus the time, calculate the number of seconds, as the name of the excel sheet, so that we can guarantee the speed of reading the database , you can ensure the file name will never repeat, the specific code as follows:

Dim D1, D2, strDiff
D2 = Now
D1 = "1970-1-1 00:00:00"
strDiff = DateDiff ("s", D1, D2)
Set theForm = Server.CreateObject ("ABCUpload4.XForm")
theForm.AbsolutePath = True
theForm.overwrite = True
'TheForm.maxuploadsize = 307200
Set theField = theForm.Files ("lukuangexcel")
strPath = Server.MapPath ("../ excel ")
%>

Set the upload form: ". Xls", the largest file is 5 megabytes, when these two conditions do not meet the time requirements will be given prompt and retransmission, when the line conditions will give a successful upload interface shown in Figure 2.


4 Conclusion urban traffic information system designed to alleviate the urban traffic pressure and reduce intersection congestion in order to reduce system development costs. ABCUpload upload component is a very practical technology, to bring programming to the programmers a lot of convenience improve the program's usage, the system uploads the file security has been fully guaranteed.
