  Accommodating pedestrians crossing midblock has been shown to have harmful
environmental consequences because of increased fuel consumption and CO2
emissions. Somewhat surprisingly, no studies were devoted to mitigating the
environmental impact of midblock crossing. Our main contribution is to propose
schemes that mitigate the increased fuel consumption and CO2 emissions due to
pedestrian midblock crossing by leveraging information about the location and
expected duration of the crossing. This information is shared in a timely
manner with approaching cars. We evaluated the impact of car decisions on fuel
consumption and emissions by exploring potential trajectories that cars may
take as a result of messages received. Our extensive simulations showed that
timely dissemination of pedestrian crossing information to approaching vehicles
can reduce fuel consumption and emissions by up to 16.7%.
