Transportation Systems Simulation - A Tutorial for Multi-Modal Simulation Using VISSIM/Bicycle: Traffic Data Input

To create the proper bike lane behavior, routes and conflict areas need to be modeled. First, place two new and separate static vehicle routes as shown below. One route directs vehicles to continue straight through without bicycles, and the other route directs only bicycles to diverge into the bicycle lane.

Add Bikes to Vehicle Compositions

1. Go to Traffic > Vehicle Compositions to open the list window. Make sure the Relative Flows sub list is chosen from the dropdown menu.
2. Right Click in the main list and Click Add… to add a new vehicle composition.
3. Then Right Click in the sub list and Click Add to add a new vehicle type, in this case bicycle.
4. Choose the speed distribution and relative flow (see Figure below). When defining vehicle inputs use the shoppesdata.xlsx vehicle composition.

Place Bicycle Routes

1. Click on Vehicle routes network object.
2. Right Click on the link prior to the bike lane divergence, then Click on the vehicle link past the divergence.
3. Repeat this process one time, except Click on the bicycle link past the divergence (see Figure below).

4. Next, Uncheck AllVehTypes for each of these new routes.
5. For the vehicle route choose all the vehicle classes, for the bike lane choose only the 60: Bike vehicle class.

To model the conflict areas use the same procedure using the Conflict Areas network object. Give priority to the bikes by using Set Status to 1 Waits for 2.
