I wanted to address this separately. In my hometown of Ventura, California, there was a merger in the mid-1970s of the two municipal bus systems (Ventura, which also provided service to the city of Ojai, and Oxnard, which similarly also served Port Hueneme) into a single joint services agency originally named South Coast Area Transit. Ventura had already, a couple of years earlier, reconfigured and expanded the old Citizens' Transit three route system that had been around since at least the 1950s into six new routes, using what was then Buenaventura Shopping Center as the hub. It worked fine with no initial problems, but eventually the same kind of issues crept in and by the time the mall was renamed Pacific View Mall in 2001 most of the stores at the north end of the property (which were not connected to the rest of the mall) were vacant, and SCAT became Gold Coast Transit six years later.
The old transit hub was essentially designated stops along one side of a driveway from the nearby street, directly east of the mall entrance. And Pacific View Mall wanted to build a multi-level parking structure which was to take out the second driveway that the buses used to get onto the mall property (JCPenney got a new store where that old parking area/transit hub was, and Target now occupies JCP's old store).
Anyway, to accommodate all that they took the parking adjacent to the closed stores, which was conveniently alongside one of Ventura's few arterial streets, Telegraph Rd., and built a transit center which remains in use today. And gradually, those empty stores to the south of it have been reoccupied: There's a Ross Dress For Less where the Thrifty Drug Store was, the old Vons supermarket is a Trader Joe's, and Barker Bros. Furniture has a 24-Hour Fitness gym occupying it now.
And the relocation of the transit actually worked better than the old hub, because there are now designated bays for every route that stops there and the only drawback is a longish walk to the mall proper. Maybe that's why they have so few problems with juvenile behavior.
(Postscript: That hub works so well that the City of Ventura approved initial planning for a second hub downtown which would also interface with Amtrak and commuter Metrolink rail service. In 2003.)
