Traffic - For a Project Not on the Caltrans Highway System
The following controls, located on the Input -> Project Information Page, are used to specify lane-based traffic counts for Local Agency projects.
eLCAP uses traffic data (cars and trucks in lanes) and the selected climate zone, to select a specific set of equation coefficients used in modeling the growth of IRI over time. The IRI is part of the GHG equation (along with lane-based car and truck counts) used during the Use Stage (see Section 2.7.2 of the eLCAP Report).

eLCAP provides two methods of specifying lane-based traffic counts:
•Using the controls shown above. First select the checkbox, and then specify AADT, AADTT and the Number of Lanes, and then select the Generate Lanes and Traffic Button. eLCAP will use the single-direction, route based AADT and AADTT, and the Number of Lanes to distribute the car and truck counts across each lane and also distribute AADTT into 2, 3, 4 and 5-axle counts for each lane.
•Use the grid below. Select the Add Lane button at the bottom and specify a value for all fields for the lane. Repeat of all lanes.

The question mark in the blue circle in the upper-right of the control group allows you to get help on the controls (this topic).
