Main Module (A-01)

 

A. Plotting Intersection and Mid-Block Accidents In 3 Dimensions On GIS Map:

·         It plots accidents on GIS map corresponding to the locations where accidents occurred. Mid-block accidents are plotted according to their relative distances or mileposts.

·         Each symbol denotes an accident. Red circles denote intersection accidents. Blue squares denote mid-block accidents. If the accidents occurred at the same location, the symbols are stacked on top of one another, creating a three-dimensional view.

·         It is easy to detect high accident locations, because they have higher stack of symbols.

·         You can select accidents to be plotted by drawing any combinations of circles, rectangles and polygons on the map, AIMS will retrieve all accidents corresponding to the specified areas and will plot them out with 3-dimensional symbols as shown in Figure A-01A below.

·         You can select accidents to be plotted through query. You can query any fields in your data; AIMS will retrieve all accidents corresponding to the query and will plot them out with 3-dimensional symbols as shown in Figure A-01A below.

·         You can specify different size, shape and color of symbols.

·         You can click a plotted symbol to see the detail accident record, because each symbol is linked to its accident record (see Figure A-01D).

·         You can add texts, lines and other drawings to the plot, and save the plot in word processor and spreadsheet programs for report purposes.

B. Plotting Collision Types In 3 Dimensions On GIS Map:

·         In additional to the 3 dimensions plotting features as described in previous page, you can plot different collision types in 3 dimensions on GIS map, as shown Figure A-01B below.

·         You can use different shapes, colors, and sizes of symbols to denote different types of collisions. For example, circles for intersection collisions, squares for mid-block collisions, yellow for rear end collisions, blue for left turn collisions, and so on.

·         You can label each plotted symbol with information from 1 to 10 fields in the accident record. For example, you can label each symbol with year, injury, fatality, and pedestrian, as shown in Figure A-01C.

·         You can assign a height factor to adjust the distance between each stacked symbol.

·         You can adjust the angle of stacked symbols (90 degree to stack vertically upward, 0 degree to stack horizontally).

·         If you order the Aerial Photograph Module (Item A-08), the collision types in 3 dimensions can be plotted on aerial photograph (see Figure A-08)

·         If you order the Accident Report Image Module (Item A-11), when you click a plotted symbol, it will display the scanned accident report image on the screen (see Figure A-11B).

C. Labeling Each Plotted Symbol With Information From 1 To 10 Fields

·         You can choose font size, type and color.

·         You can set up meaningful expressions. For example, if the expression is “Yr=” + Field1_value + “, Inj#=” + Field2_value + “, Kill#=” + Field3_value + “, Ped#=” + Field4_value, then the label will look like A-01C as shown below.

·         You can adjust the size, distance and stack angle of the symbols.

·         The label will be clear and sharp in zoom-in view because the plot is in vector format.

D. Displaying Detail Record Information Associated With Each Plotted Symbol

·         You can adjust the size, distance and stack angle of the symbols.

·         You can zoom-in to pick the desired symbol for displaying its detail record information.

Computer Requirements:

Hardware:    Computer with 1GB or more RAM, 100 GB or more hard disk space.

Software:     Windowsâ (10 or 11) and a GIS map of your jurisdiction.

           

GIS Platforms:

·         AIMS interfaces with ArcGIS 9X or later and MapInfo Professional 8X or later.

·         It can use data and map from ArcGIS, MapInfo, Geomedia, TIGER, etc.

 

Intersection & Non-intersection Accidents:

·         You can analyze intersection and non-intersection (mid-block) accidents.

 

3-Dimensional Plots:

Plotting Intersection and Mid-Block Accidents In 3 Dimensions On GIS Map:

·         It plots accidents on GIS map corresponding to the locations where accidents occurred. Mid-block accidents are plotted according to their relative distances or mileposts.

·         Each symbol denotes an accident. Red circles denote intersection accidents. Blue squares denote mid-block accidents. If the accidents occurred at the same location, the symbols are stacked on top of one another, creating a three-dimensional view.

·         It is easy to detect high accident locations, because they have higher stack of symbols.

·         You can select accidents to be plotted by drawing any combinations of circles, rectangles and polygons on the map, AIMS will retrieve all accidents corresponding to the specified areas and will plot them out with 3-dimensional symbols as shown in Figure A-01A.

·         You can select accidents to be plotted through query. You can query any fields; AIMS will retrieve all accidents according to the query and will plot them out with 3-dimensional symbols as shown in Figure A-01A.

·         You can specify different size, shape and color of symbols.

·         You can click a plotted symbol to see the detail accident record, because each symbol is linked to its accident record (see Figure A-01D).

·         You can add texts, lines and other drawings to the plot, and save the plot in word processor and spreadsheet programs for report purposes.

Plotting Collision Types In 3 Dimensions On GIS Map:

·         You can plot different collision types in 3 dimensions on GIS map as shown in Figure A-01B.

·         You can use different shapes, colors, and sizes of symbols to denote different types of collisions.

·         You can label each plotted symbol with information from 1 to 10 fields in the accident record. For example, you can label each symbol with year, injury, fatality, and pedestrian, as shown in Figure A-01C.

Pin Map or Plot Generation Capabilities:

It produces a plot or pin map for the accident locations you clicked on map. It also produces a plot or pin map from your query or sorting. Hence it can produce unlimited number of user-specified pin maps or plots.

          In addition, it produces over 10 standard reports. Standard plots are pre-programmed pin maps, user simply clicks a button, and the plot will automatically be generated. The standard plots include:

·         A pin map showing all accident locations within the whole jurisdiction. 

·         A pin map of the worst 100 accident locations.

·         A pin map of all locations with red-light violation accidents.

·         A pin map of all locations with drunk-driving accidents.

·         A pin map of all locations with speeding accidents.

          The above pin maps use 3-dimensional symbols as described under 3-Dimensional Plots. That is, locations with higher accidents will have higher stacks of symbols. You can visualize where are the hot spots. As new data are entered, these reports and plots will be updated to reflect the status. 

 

Report Generation Capabilities:

As mentioned under Query Capabilities, you can perform unlimited number of queries. Each query result is a report. Hence you can generate unlimited number of reports to meet your needs.

          In addition, it produces over 30 standard reports. Standard reports are pre-programmed reports, user simply clicks a button, and the report will automatically be generated. The standard reports include:  

·         Number of accidents for every location within the jurisdiction.
