Re: [sumo-dev] Lead vehicle type in Wiedemann car-following model

2018-04-08 Thread Jakob Erdmann

Hello,
The value of pred may be a nullpointer in some calling contects among which
is lane-changing (the followspeed function is not only used when
car-following but also when determining appropriate gaps for
lane-changing). Therefore, instead of
std::cout << " pred ID=" << pred->getID();
use
if (pred != 0) {
  std::cout << " pred ID=" << pred->getID();
}

Re: [sumo-dev] Lead vehicle type in Wiedemann car-following model

2018-04-05 Thread Jakob Erdmann

The function MSCFModel_Wiedemann::_v does not have access to the lead
vehicle.
You must either add another parameter to that function and modify the call
to _v in MSCFModel_Wiedemann::followSpeed or you just do your printing in
MSCFModel_Wiedemann::followSpeed before the call to _v (i.e. pred->getID()).
I advise seeking programming guidance on your campus as you will run into
lots of questions like these and general programming help is beyond the
scope of this mailing list.

Jakob

Re: [sumo-dev] Lead vehicle type in Wiedemann car-following model

2018-04-05 Thread Umair Durrani

Thanks for your help.

Coming back to the lead vehicle, how do I use the pred object? To clarify,
I mean that for the veh object I get the information from MSVehicle.h and
MSVehicleType.h files. For example within the _v() function, I can do:

std::cout << veh->getID();

But where do I get the ID and other attributes of pred?  Could you please
give me an example of printing the lead vehicle ID and type/class in the _v()
function?

I am really thankful for your patience and help.

 Hi Jakob,

 Thanks for your reply. I see that you made changes few hours ago.  I'm
 very new to git/github and developement so please bear with me.

 Based on the commit ID you provided, I found that the changes are shown
 on this URL: https://github.com/DLR-TS/sumo/commit/8f43c4a6874690c0a
 41443b1efbead0e4384f921

 So, I thought when I download the development version from this link: (
 http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version)
 I'd get the new files

 However, I don't see any changes in the files. Where can I download the
 latest development version that includes those followSpeed() changes that
 you recently made?

You need a working installation of python and then the version.h file is

Thanks. I have downloaded it from github.

However, when I build it I get an error:  Cannot open include file:
'version.h': No such file or directory

So, I opened an github issue:  Error: Cannot open include file:

 Hi,

 I am looking into the Wiedemann model and related
 .
 cpp and .h files in the development version of SUMO.

 Is there a way to print or do something with the LEAD vehicle type in
 the MSCFModel_Wiedemann.cpp?. I found 'gap2pred' and 'predspeed' but
 nothing like 'predType' or 'predClass'.

 Ideally, I want to change the behavior of following vehicle if the lead
 vehicle class is a truck.

Re: [sumo-dev] Lead vehicle type in Wiedemann car-following model

2018-04-05 Thread Umair Durrani

Hi Jakob,

Thanks for your reply. I see that you made changes few hours ago.  I'm very
new to git/github and developement so please bear with me.

Based on the commit ID you provided, I found that the changes are shown on
this URL:
https://github.com/DLR-TS/sumo/commit/8f43c4a6874690c0a41443b1efbead0e4384f921


So, I thought when I download the development version from this link: (
http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version)  I'd
get the new files

However, I don't see any changes in the files. Where can I download the
latest development version that includes those followSpeed() changes that
you recently made?

Hello,
in the very latest development version
(8f43c4a6874690c0a41443b1efbead0e4384f921) the followSpeed() API includes a
parameter for the lead vehicle. Note, that in some calling contexts, this
value may be a nullpointer

Jakob
