Boston police are preparing for a busy two-day stretch, dedicating additional officers and resources to Allston Monday for a streetside Aerosmith concert and, on Tuesday, to hundreds of polling stations throughout the city for Election Day voting.

Both days will involve road closures, parking bans, and traffic diversion. The department is coordinating with the Secret Service and State Police to provide security for Republican presidential candidate Mitt Romney’s election-night rally at the Boston Convention and Exhibition Center, police Superintendent in Chief Daniel P. Linskey said Sunday.
