Bug: transit improvements not posting

[lisette-solis]

Transit improvement boolean question is not posting correctly.

models.py
   # Page 3:
    satisfied = models.IntegerField(choices=SATISFIED, null=True)
    transit_improvement_service = models.IntegerField(choices=BOOL_CHOICES, null=True)
    transit_improvement_schedule = models.IntegerField(choices=BOOL_CHOICES, null=True)
    transit_improvement_transfers = models.IntegerField(choices=BOOL_CHOICES, null=True)
    transit_improvement_safety = models.IntegerField(choices=BOOL_CHOICES, null=True)

Proposed fix
Use map options to integer and implement dropdown in the same way as other questions.
