You can roam the city when not on a case.
Every time you finish a desk (traffic, homicide, vice etc) you are given the ability to free roam - street crimes specific to each desk have to be completed.
To go to free roam, go to cases, and then scroll down to the bottom of a desk (traffic is the first "desk" you complete that has free roam) you have finished and the option to free roam will be there.
