function varargout = traffic_flow(varargin)
% TRAFFIC_FLOW M-file for traffic_flow.fig
%      TRAFFIC_FLOW, by itself, creates a new TRAFFIC_FLOW or raises the existing
%      singleton*.
%
%      H = TRAFFIC_FLOW returns the handle to a new TRAFFIC_FLOW or the handle to
%      the existing singleton*.
%
%      TRAFFIC_FLOW('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TRAFFIC_FLOW.M with the given input arguments.
%
%      TRAFFIC_FLOW('Property','Value',...) creates a new TRAFFIC_FLOW or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before traffic_flow_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to traffic_flow_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
