show vClass-specific speeds in lane parameter dialog

Can I please work on this?

To my understanding, we should add new mkItem calls in GUILane::getParameterWindow() of the src/guisim/GUILane.cpp file. Is this correct?

[namdre]

Yes and yes. The new items should only be shown if the lane has vClass-specific speeds. The attribute name should be something like:

maxspeed [m/s]         |  27.78
    maxspeed (truck)   |  16.67

with a slight indent to make it from a group with the default maxspeed [m/s] item

Awesome, thanks! Will work on it and make a PR soon.

and can we please rename the line to "allowed speed"?

[vijay-jaisankar]

Sure thing! Will do

Hello, while working on this, I faced an issue. This is the code so far:

if(MSNet::getInstance()->getRestrictions(myEdge->getEdgeType()) != nullptr){
        auto map = MSNet::getInstance()->getRestrictions(myEdge->getEdgeType());
        for (auto item = map->begin(); item != map->end(); item++) {
            SUMOVehicleClass svc = item->first;
            double speed = item->second;
            // Convert svc into a string 
            // mkItem call
    }

Can you please let me know if

• I'm on the right track
• If yes, how do you convert the svc object into a string for the mkItem call? I tried c_str() but it didn't work.
• If not, which other function call I should focus on instead.

Thanks, Vijay

You can simply use toString(svc) to convert it into a string
