Crash Magic features that require GIS

Issue

Crash Magic version 4 & version 5 can take advantage of an ArcGIS Server installation to provide additional functionality in the program  This article describes what those features are and what is required to take advantage of them.

Explanation

The new features that take advantage of GIS functionality are as follows:

Click-on satelite view [built-in]
To display Google map depicting crash location in diagram click-on. Either crash must include a latitude and a longitude field or street, cross street and local agency.1
Crash pin maps and heat maps [built-in]
To display pin maps depicting crashes in Crash Magic, the crash data must include a latitude and a longitude field.1
Study selection from online map
Study selection from a map – coordinate rectangle [lat/long data]
Crash Magic provides the ability to select a rectangular area from a map and create a new study and report of crashes in that rectangle. This functionality requires latitude and longitude fields in the crash data to complete the selection.
Study selection from a map – intersection point [built-in]
Selection by point is under development.  When complete, Crash Magic will provide the ability to select a point which it will then resolve to an intersection name and create a new study and report of crashes at that location. This functionality does not require any new resources.
Collision diagrams
Legacy collision diagrams [built-in]
Our legacy collision diagrams, in use since 1987 do not require any GIS functionality.
Standard collision diagrams [ArcGIS Server:center-line + geocoder]
The first of your new types of diagrams require an ArcGIS Server with a center-line map service and a geocode service.
Dynamic collision diagrams [ArcGIS Server:center-line + geocoder]
The second of our new types of diagrams require an ArcGIS Server with a center-line map service and a geocode service.
Dynamic corridor collision diagrams [ArcGIS Server:center-line + geocoder]
Dynamic corridors which depict a length of roadway from one intersection to another, are still in development. When released, they will have the same requirements as “Dynamic collision diagrams” above.
Geocoding [ArcGIS Server:center-line + geocoder]
A new service available from Pd’ Programming is geocoding of your crash data. Crashes may be geocoded based on street name and address or by intersection name plus distance and direction from the intersection. This service requires an ArcGIS Server with a compatible street center-line service and geocode service. There is an an additional annual fee for our geocoding service.
——————————
1. Latitude and longitude must be in WGS84 coordinate system. See http://epsg.io/4326. If coordinate data is provided in a projected coordinate system (e.g. state plane), it must be converted to latitude and longitude for use in the program. This may be done prior to import, or we can arrange to make this conversion on our servers periodically.
