Veins Multiple Applications in multiples Vehicle types

阅读更多关于 Veins Multiple Applications in multiples Vehicle types

问题 in my simulation using OMNeT++, Veins, and SUMO i want run multiple applications according to their vehicle type, as specified in the .rou.xml file using type="XXX" For example: <vehicle ... type="private" ... > runs APP_private (using something like *.node[*].applType ="APP_private" ) <vehicle ... type="bus" ... > runs APP_bus (using something like *.node[*].applType ="APP_bus" ) How can I define this in omnetpp.ini ? 回答1: Veins 4.6 allows you to set any or all of the moduleType , moduleName

SUMO traci接口python编程学习

阅读更多关于 SUMO traci接口python编程学习

入门运行小例子刚开始学习在python当中引用traci接口的时候，可以先去看sumo工具中给出的例子，路径为$SUMO_HOME/docs/tutorial/。里面有几个文件夹，如下图，以traci_tls为例，是用来修改仿真中信号灯信息的python脚本。运行例子：先进入所在的路径下，之后python traci_tls运行，就完成了一个小例子啦！之前遇到运行不出来的情况，最后知道是没有先cd到这个路径下，就会报错很多文件找不到的情况～ # 二、SUMO工具包这些工具都可以在sumo的tools文件夹下面找到。一般它们都是微小的——都是用于在特定命令下的特定用途，但是在其他情况系可能无效。注意这些工具一直是在改进的，有相关信息可以访问：。很多工具都是直接在tools文件夹下的，很多过时的将被转移到tools/purgatory中。这些工具按照以下分类： assign——交通分配工具 bulid——用于代码样式和子系统的工具 detector——一些用于处理真实世界中回路线圈数据的工具 district——用于处理TAZ（交通分析区域，trafficanalysis zones），又名districts import——用于处理非SUMO的数据导入（1）osm——处理OpenStreetMap数据的工具（2）visum——处理VISUM数据的工具（3

问题 I am starting to use Omnet++ with veins for VANET simulations, but at the end of the tutorial (http://veins.car2x.org/tutorial/), where it says to go into the IDE and click "Run As > OMNeT++ simulation", an error occured : Cannot evaluate parameter 'headerLength': (omnetpp::cDoubleParImpl)headerLength: Cannot cast from type double to integer - in module (Mac1609_4) RSUEXAMPLESCENARIO.rsu[0].nic.mac1609_4 (id=12), during network initialization. Ok, it crash trying to cast int from double, but

wx Module misses attribute ArtProvider

问题 I am adapting a model in SUMO and try to run a file (sumopy_gui.py). When doing so I get the following error message: AttributeError: module 'wx' has no attribute 'ArtProvider_GetBitmap' I tried to update wx in the cmd line, reinstalling it, but I don't find a reason why wx shouldn't have this module. All the other modules seem to be working for now. Can someone help me please? Thanks 回答1: If you are using wxPython 4, then you want to use wx.ArtProvider.GetBitmap . Previous versions (i.e.

How to set speeds using a pandas dataframe in SUMO with TraCI?

阅读更多关于 How to set speeds using a pandas dataframe in SUMO with TraCI?

问题 Objective I want to use predefined speed vectors for individual vehicles to move them in SUMO simulation. Data and files There are 3 vehicles in the simulation. For 2 of those vehicles, I want to specify the speeds. The speed data is created in Python as follows: import numpy as np import pandas as pd from pandas import Series, DataFrame data = {'ADO_name':['car1','car1','car1','car2','car2','car2'], 'Time_sec':[0,1,2,0,1,2], 'Speed.kph':[50,51,52,0,0,52]} dframe = DataFrame(data) The route,

How to disable lane changes in SuMO?

阅读更多关于 How to disable lane changes in SuMO?

问题 I am using a TraCI call to set the lane change mode of a vehicle to 0 to disable all lane changing: TraCICommandInterface::setLaneChangeMode(0b000000000000); However, the vehicle still does a lane change afterwards. I also tried 256 (i.e. 0b000100000000 and 512 (i.e. 0b001000000000 ) as indicated in the wiki or in this post. It seems that the executed lane change action was queued earlier (i.e. before the TraCI call), because the vehicle is flashing its turn light, and could not be executed

Multiple python client objects connecting to one sumo simulation

阅读更多关于 Multiple python client objects connecting to one sumo simulation

问题 I am new in SUMO. I have a .net, a .rou (containing 300 vehicles with vehicle depart, id, route edges attributes), a .trip and a .sumoconfig file representing a traffic scenario. I want to create these 300 vehicles as python Vehicle object generating from a Vehicle class containing other functions to communicate with each other. How can they connect dynamically to sumo and get linked to those 300 cars in the scenario? I can write a server that listens for these objects and accepts connection

What happens to vehicles when they end their route?

阅读更多关于 What happens to vehicles when they end their route?

问题 My project is to build a VANET-based smart parking simulation for a small-scale urban area. I dynamically define a route for vehicles to traverse to, then park for ' x ' amount of time. Implementation for that is complete, the next step was to define a new exit route for them to exit the simulation after the ' x ' amount of time is up. Reason being is that I want to simulate cars vacating parking spaces so that other vehicles may be able to avail of them (I don't want them to simply just to

Veins can now “simulate cars without network cards” - Documentation?

阅读更多关于 Veins can now “simulate cars without network cards” - Documentation?

问题 Dear OMNET/Veins community, I noticed in the Changelog under Veins v4.3 that there is now capability for simulating vehicles without network cards. Would there be any documentation / or instructional material available to help the user take advantage of this new capability? Thanks so much, Van 回答1: You can take advantage of this insofar as you can now remove the module simulating a network card (the NIC module) from a car without the simulation complaining (it used to throw an error, noting

How to control the transmission power and speed based on the distance between two vehicles in Veins

阅读更多关于 How to control the transmission power and speed based on the distance between two vehicles in Veins

问题 I am a beginner about Veins. Now I am trying to simulate dynamic adjustment of the transmission power and speed between 2 running vehicles based on their distance with each other with Veins 4.5, Omnet 5.0 and Sumo 0.29. So far I have built the Sumo model and run the model in Omnet but without any programming which means the transmission power and speed between 2 vehicles are all set in the .ini file. Now I want to implement an algorithm to adjust them dynamically. As a beginner I barely know
