The most important problem in our city is its poor public transportation system. Thousands of residents rely on the city's buses and taxis to travel throughout this large city,
while the Metro Transportation System's daily schedules are totally unreliable. A bus or taxi
that should arrive at 7:45 may not arrive until 8:00 or later. Moreover, it is not unusual for a
bus driver to up groups of people waiting for the bus because he wants to make up for lost
time. Unfortunately, people often end up going to work late or missing important
appointments. In order for people to get to their destinations on time, people must allow for
waiting time at the bus and taxis stops.
