[sumo-user] Changing maximum speed limit of all the vehicles in a simulation at a given time.

Hello Everyone! I am trying to change the maximum speed of all the vehicles that are currently at this instant in the SUMO simulation using TraCI. May I know how I can execute this? Thanks and Regards, PSK ___ sumo-user mailing list

[sumo-user] Using crowd-sourced GPS data for generating simulation

Are there any tools available that make it possible to generate a simulation using crowd-sourced GPS movement data (e.g. Google Maps or Tom-Tom)? I find this to be more appealing than using ActivityGen or SAGA, as the simulation is using directly measured data, rather than using survey data.

[sumo-user] How to measure the distance between the ego vehicle and neighbor vehicles in the current lane

Hi, I was wondering to know how the distance between the ego vehicle and neighbor vehicles in the current lane is measured. I tried getNeighbors command, but it only gives the information of neighbors on the left lane or right lane. Thank you in advance. Regards, Reza. -- Sent from:

Re: [sumo-user] Manually controlled vehicles

Thank you for your reply. I am using the TraCI commands to create vehicles and control them by changing tau, setSpeed. But it is not moving a vehicle closer to the leading vehicle. Best regards On Thu, Jul 2, 2020 at 2:48 PM Padisala, Shanthan Kumar < padisal...@buckeyemail.osu.edu> wrote: >

You can instead use TraCI commands to define the vehicle and control it. -PSK From: sumo-user-boun...@eclipse.org on behalf of Traboulsi, Abdullah Sent: Thursday, July 2, 2020 2:43:49 PM To: Sumo project User discussions Subject: [sumo-user] Manually

[sumo-user] Manually controlled vehicles

Hi, I am trying to take complete control of vehicle speed acceleration ..etc. But whenever I define vehicles using tags in routes and run the simulation, it will be automatically assigned with Car Following Model and LCModel. These models will control the vehicle using the defined algorithm. Is

Re: [sumo-user] Simplifying Activity-Based Demand Generation

I recommend that you take a look at SAGA instead of activitygen (which is not being maintained for some years): https://github.com/lcodeca/SUMOActivityGen/blob/master/docs/SUMOActivityGen.md Am Do., 2. Juli 2020 um 15:15 Uhr schrieb Chris Abraham : > Hi everyone. I am fairly new to Sumo, and

[sumo-user] Simplifying Activity-Based Demand Generation

Hi everyone. I am fairly new to Sumo, and would like to know if the approach I am taking is correct. I am trying to generate a simulation of a city using `ActivityGen`. I have most of the statistics needed for the stat file. However, I am struggling to fill in one part of the stat file - the

[sumo-user] Number of vehicles in Car Following Model

Hi Jakob, I wanted to ask if there were a limit to the number of vehicles in a platoon of Car Following Models? For example, I am generating 10 vehicles every 10 steps with the same tau and sigma, but every 4 vehicles are following each other. I have attached my Routes file as well as

Re: [sumo-user] (no subject)

Attribute density reports density per edge which gives you twice the number of vehicles for a two-lane edge. You can use laneDensity since version 1.6.0 for the scaled value. Am Do., 2. Juli 2020 um 14:27 Uhr schrieb Amirhosein Karbasi < amirhosein.karbas...@gmail.com>: > hi Jakob, > I have 2

hi Jakob, I have 2 lane freeway and I used edge data. my min gap is 2.5 and vehicle length is 5 .so my jam density should be nearly 133 vehicle/km but in my edge data jam density is nearly 260 vehicle/km.what is the problem? ___ sumo-user mailing list

Re: [sumo-user] speed

departSpeed="max" automatically reduces insertion speed at low time headways. To achieve reliably high insertion speed, either - reduce traffic flow - use departSpeed="desired" (but also see https://sumo.dlr.de/docs/Simulation/VehicleInsertion.html#effect_of_simulation_step-length ) regards,

hello, dear Jakob, I have a 3 lane freeway and I set maxSpeed="36.11" laneChangeModel="LC2013" for vehicles and set departPos="base" departSpeed="max" departLane="best" for routes . but in free flow speed average speed is about 13 m/s . what is the problem ?

Re: [sumo-user] Gap acceptance in lane changing

In your scenario most of the changing happens from the on-ramp and is aided by cooperative lane-changing of the main flow (main-flow vehicles move away from the right lane to let ramp vehicles merge). You will see an effect of lcAssertive (and also from tau) if you either - increase traffic -
