[sumo-user] car following models
Dear Sir/Mam, I would like to use ACC or CACC car following model in SUMO created runtime using TraCI (matlab). Could you please let me know what is the exact typeID I need to mention or where can I see the possible values? Such as for IDM I'm using ''Follow_IDM".

[sumo-user] Information regarding car-following model
Dear Jakob, I'm using IDM car following model in my simulation for normal traffic as well as to form vehicle platoons. Though I'm controlling platooning vehicle's speed in order to maintain constant intra platoon gap. Could you please suggest if IDM car following model is suitable for vehicle platooning or I need to use some other model?

[sumo-user] Fuel consumption in sumo
Hi Jacob, Could you please clarify, is the fuel consumption of a vehicle in any timestamp depends on only its speed or any other parameters like accel/decel. I was checking the output file, in some cases, it is showing fuel consumption is 0 through the vehicle has some speed. Is there any link which explains how the fuel consumption is computed?

I thought it's 31. In my simulation, I first made the speed mode as 0 that makes all checks off. In next simulation step when I'm resetting the speed mode in 31, the vehicles are moving at constant speed. They are not accelerating even if the lane is empty. I'm working in traci-matlab.

Re: [sumo-user] Default speed mode value used in Sumo
Hi Jacob, Please find the sample example code rough.m . The initial vehicle speed is 2 m/s and it is increasing as per accel. speedmode is set to 0. Later, speed is increased and speedmode is set back to 31. But, the speed of the vehicle remains same 20m/s. Can you please tell me where is the mistake here?

[sumo-user] Default speed mode value used in Sumo
Hi Jacob, Could you please tell me what is the default speed mode value used in Sumo, where the vehicles speed up if the lane is free? I thought it's 31. In my simulation, I first made the speed mode as 0 that makes all checks off. In next simulation step when I'm resetting the speed mode in 31, the vehicles are moving at constant speed. They are not accelerating even if the lane is empty. I'm working in traci-matlab.

[sumo-user] Vehicle speed for next step
Hi Team, Is there any function available to get the speed of a vehicle for the next step. For example, if I'm in ith simulation step, I want to know the speed of a vehicle for i+1 step. In general, it becomes speed+acc for a free road. But, if there are other traffics as well, what will be the speed? I'm using IDM car-following model in sumo-matlab platform. I've also tried to calculate the speed as per IDM car following model, but it is differing a bit like (+/-1 m/s^2) from the actual one. Can you please suggest.
