title: Vehicle Speed change (runner.py file) in SUMO Simulation
body: <p>I am trying to use TraCI commands in "runner.py" file and in the wiki for TraCI the commands are presented in octal format or so.
  How to configure the behavior of vehicle in "runner.py" file ?</p>
  
  <p><strong>Can we change the parameters of the vehicle dynamically (change in speed during simulation) ?</strong></p>
  
  <ol>
  <li><p>Change the speed of the specified vehicle(s) to the given value over the given amount of time in milliseconds (increase/decrease to decrease/increase speed). I guess that would happen only using TraCI commands.If so, in what format i can use those commands?</p></li>
  <li><p>If there is traffic on the current lane, the vehicle should be able to switch to next lane accordingly.</p></li>
  <li><p>How to control the vehicles not to undergo random lane change ?</p></li>
  </ol>
  
  <p>I would really appreciate if someone could help me to sort out this.
  Thanks in advance</p>
