Intersection Magic has been designed to support a wide variety of data formats. This data may originate on a mainframe, mini, or micro computer. In some areas data may be obtained directly from the state, California, Iowa, Oregon, Arizona and Idaho to name a few. In other areas, data is stored at police departments on mainframes. In still others, data is maintained on PC database programs. Intersection Magic supports all of these cases.

We would like users to be able to take advantage of a new way to backup and copy their configurations.
When Intersection Magic updates are sent to users, the 'custom configuration' that was sent for the first install is not included with the update cd or diskettes. The result is that, for a network install, no data directory (containing imwuser.exe) is created, and thus the 'client' side of the install can not take place. For a local install, only the demo/tutorial is installed, there is not IMW icon or DATA directory.
Making the Address or Mile Post fields blank in IMW Edit will store invalid numeric values in the database for those fields, and can cause program crashes.

CA CHP introduced a new structure for SWITRS data beginning with data send after June 2002 (although most of this new format didn't ship until 2003) Pd' Programming made available a new configuration to read this data free-of-charge to all current subscribers to our Intersection Magic software. On February 13, 2003 we identified a minor problem with the new configuration. The caseID format in this new CHP data structure is variable - it is different after 1/1/2000. This article describes how to correct your configuration and database if you downloaded the new configuration prior to 2/18/2003 and imported 2002 data using it.
Intersection Magic provides a mechanism for "pushing" configuration and master support files (schematics, charts, gis, scripts, and other misc files) from a server to each local installation. This mechanism only works when a full network install is used. This article provides a checklist to follow if this mechanism isn't working.
A feature exists in the Pd' Editor application (pdeditor.exe) that provides the ability to produce a list of every intersection within a virtual corridor as well as all of its aliases.

User receives an error message stating trial period has expired or no active database when using the IMW Editor.
Intersection Magic's symbols to represent vehicles, fixed objects, dui, etc. reside in a symbol library that can be modified. Therefore, new symbols can be created and then introduced into the object table (.tbs) file and displayed in collision diagrams.
Intersection Magic keeps track of users who are accessing the database. At any one time there may be many people READING from the database. However, if anyone is writing to the database, no one else may READ or WRITE at the same time. If you are attempting to READ when you get this message, then another use has opened the database for WRITING. If you attempting to WRITE to the database, then another user is READING the database. Note: This message can also be caused by the program having crashed during a READ or WRITE operation and not released its lock on the database.

Intersection Magic is 'configured' for a particular format of ASCII data. When you first purchased IMW, we probably prepared a custom configuration. This custom configuration defines, among other things, the order of the fields in the ASCII import file; the meanings of any coded fields; the method of parsing, or extracting the data from any given field. Periodically, states re-evaluate the crash report form that they are using. When this is done, they frequently add or remove fields. Occasionally, they add or remove codes for a particular fields. Rarely, and unfortunately, they change the value that a code represents in a particular field. This article describes some things to think about if you find that your data source is different than it was when we prepared your configuration.
This problem occurs when your printer is set to a resolution higher than 300dpi. Intersection Magic is still printing to some internal coordinates that reflect 300dpi.
In some cases street names appear twice in cross streets listings and that it can cause confusion when selecting street names.

Changes made in version 6.615 require user verification of cross-street data. Note that because the changes only affect cross street ordering associated with the use of aliases, this information only applies to users who have prepared cross street listings using the streets manager. Also, if aliases have never been used, this information does not apply.

This article describes some general "try this first" printer problem solutions.
Each diagram contains a number at the top that indicates how many crashes took place at that location. The number of graphics may not always match that number. However, the number of graphics plus the number of "records with insufficient data for display" listed at the bottom of the diagram should match.

Is there a way to get a accident listing along the entire length of a roadway? Yes. There are several ways. This article describes the various ways to obtain that data.
On occasion, users have the need to supplement records in their database without removing data already stored for those records. An example would be if you have a data source that provides you all the crash data you need except for direction from intersection. You have another source that can provide direction from intersection and uses the same caseid number that the first data source uses. This is a use for Supplemental importing.
When there are greater than 16,000 accidents to be generated on an all-data diagram, the program may crash.
Accident graphics are placed on the collision diagrams automatically. As a result, they will never be as good as those done by hand by a trained technician. However, there are may way to improve the display of a diagram. Those methods are described in this document.
Under certain circumstances, especially when an Intersection Magic program directory is copied from one computer to another, many settings come along with it that may confuse Windows or Intersection Magic. The result is that the program may not permit printing, changing printers, or configuring printers.

When in the data entry program - imwedit.exe, the computer beeps when enter or tab is pressed rather than moving from field to field as intended.
You want to create a single chart that shows the day of the week accidents occurred - but want several specific intersections on that one chart.
It would appear that there are two streets with the same name causing reports to list a street twice.
The data in Intersection Magic is usually obtained from local city, county or state sources. In most cases, it is possible to query these sources to list the same data being reported by Intersection Magic. WeÕve found that when this is done, there may be discrepancies between the two systems. There can be several causes for these discrepancies. This document describes how we attempt to identify and resolve these differences when contacted by a concerned user of our software. While we welcome you to contact us, it is our hope that you can take the first steps yourself using the information provided here.
The California Highway Patrol (CHP) maintains the crash records that you use as SWITRS data. In January of 1998 they modified the format which had been used for many years. The format was changed to add the century to any dates in the data file. This makes the data y2k compatible. This requires special treatment of SWITRS data by Intersection Magic.
Can't re-index after installing latest version of IMW. Warning (see summary) indicated.
Since the earliest version of Intersection Magic, the install program has looked for a file called cityid.txt to identify configurations to include in the install process. This file always needs to be included in the data directory of the install diskette, and on the hard disk. Beginning with version 6.002, this cityid.txt file is also used by the Intersection Magic program to identify that it is running in a valid directory, and to describe the configuration. This article describes how to create such a file.
