Higher Speeds

I am a student in a local school and I believe safety is important in terms of sidewalks because it keeps pedestrians off the street. Saying this I think we should raise the speed limit because 30 km/h is very slow and it's hard to get anywhere on time with that speed. The streets are much more safe with the sidewalks in place and since the street is wide the pedestrians are even further from the cars than before giving them extra safety. I think a good speed limit is 40 Km/h. This speed should be okay because there are no schools on that street, there is only a very small park and on that block you can put up a playground sign so people will slow down.
