Output Database Definition¶
Aimsun Next has a generic format that accommodates data from macro, meso, micro, and hybrid experiments. The application generates two sets of tables: one that contains the information about what has been stored (meta information tables) and another with the information itself (information tables). Information tables are always stored in metric units.
Note: Density (veh/km) is calculated per lane, not section. Because a section can contain two or more lanes, please be aware of the impact of the number of lanes on the output value. For example, a single vehicle in a kilometer-long section with three lanes would return a density value of 0.33.
Meta Information Tables¶
Aimsun Next will store information about the object that has generated the data into the SIM_INFO table and information about the data itself in the META_INFO, META_SUB_INFO, and META_COLS tables.
To see more specific information about a specific type of experiment refer to the following examples:
- Vehicle-Based Simulator Meta Information Table Examples
- Macroscopic Model Meta Information Table Examples
- Travel Demand Model Meta Information Table Examples

Information Tables¶
Information tables vary from model to model but they have a common structure. The name of an information table has a prefix to indicate the model that has generated it:
- MI: Aimsun Next Micro
- ME: Aimsun Next Meso
- MA: Aimsun Next Macro
- HY: Aimsun Next Hybrid
The common structure is:
| Attribute name | Type | Description |
|---|---|---|
| did | INTEGER | ID of the replication/ average /experiment that generates this data |
| oid | INTEGER | ID of the objects that generates this data |
| eid | VARCHAR(128) | External ID of the object that generates this data |
| sid | INTEGER | Subobject position (as set in META_SUB_INFO) |
| ent | INTEGER | Interval number, from 1 to N and 0 reserved for the aggregated value |
After these common fields, a list of fields with the effective information appears. Each field is listed twice, once with the value, another one with the standard deviation. The name of the fields are listed in the META_COLS table. The standard deviation field name is created adding the suffix _D to the field name. For example: speed and speed_D. If a field has no standard deviation (its aggregation type is Sum) then the second field does not appear.
Aimsun Next has a generic format that accommodates data from macro, meso, micro, and hybrid experiments. The application generates two set of tables, one that contains the information about what has been stored (meta information tables) and another with the information itself (information tables). Information tables are always stored in metric units.

Information Table Examples¶
Based on the previous tables we know that we have two information tables (MISYS and MISECT) with 6 intervals (the simulation duration is one hour, the gathering interval is 600 seconds) plus an aggregated one and three vehicle types (0 for All, 1 for car, 2 for van). The fields listed as aggtype 2 will have both the value and the standard deviation (speed and speed_D) and the fields as aggtype 3 will have only the value (density).
For the sections, we will list two objects (oid: 265 and 266), for the system just one, the replication (oid 285). For all the tables, the did value will be 285 as this is the ID of the replication that has generated all the tables. An example of the MISECT table showing just density and speed for the first 2 intervals and the aggregated one (ent) and three vehicle types (sid) for section 265 (oid) follows:
| did | oid | eid | sid | ent | density | speed | speed_D |
|---|---|---|---|---|---|---|---|
| 285 | 265 | 0 | 0 | 9.12276 | 54.0288 | 4.27335 | |
| 285 | 265 | 1 | 0 | 9.12276 | 54.0288 | 4.27335 | |
| 285 | 265 | 2 | 0 | 0 | -1 | -1 | |
| 285 | 265 | 0 | 1 | 9.37195 | 54.2844 | 3.83625 | |
| 285 | 265 | 1 | 1 | 9.37195 | 54.2844 | 3.83625 | |
| 285 | 265 | 2 | 1 | 0 | -1 | -1 | |

| 285 | 265 | 1 | 2 | 9.22609 | 53.9951 | 4.35469 | |
| 285 | 265 | 2 | 2 | 0 | -1 | -1 |

London Emission Model ¶
The LEM family of tables contains the emissions outputs for CO2 and NOx for sections (g/km), links (g/h) and the replication (g).
The replication value (g) is the sum of the emissions (g/km) of every vehicle in each traveled section multiplied by section length (km).
This is because the model only considers the pollution emitted by a vehicle in some point with a certain speed, hence turns are not taken into consideration in the total sum of emissions.
The LEM model is documented in the Environmental Models: London Emission Model section.

Static Assignment Model Tables¶
The Tables defined in the Aimsun Next Static Assignment Results Database are: MASECT, MATURN, MACON, MATRAJ, MADET, MAROU and PLCONV. As these tables are derived from a single experiment with no replications and no random variation, there are no "_D" table attributes giving the standard deviation of the results. The calculations made to find the link costs are coded in the Static Macro VDF (Volume Delay Functions), the Static Macro TPF (Turn Penalty Functions), the Static Macro JDF (Junction Delay Functions), and the Static Macro Function Components. The calculations made to estimate the corresponding flows depend on the type of assignment chosen. This is documented in the Static Traffic Assignment: User Equilibrium Models Section
