Because of an oversight in city law, the city would have forbidden visitors and residents from taking shuttles and limos. Until Tuesday, they could have only taken cabs.

But because Outdoor Retailer brings in so many visitors, all forms of ground transportation must be available. So to accommodate the Aug. 11-14 show, the City Council approved a stopgap ordinance to fix the problem.

The rules are complex - a matrix was formed to explain them - and they allow certain types of transportation based on whether trips are on-demand (spur of the moment) or pre-arranged (called in 30 minutes in advance).

Essentially, taxicabs can be used whether the trips are pre-arranged or on-demand. Limousines, too, but the city will require passengers pay an extra $30 fee for on-demand trips.

Hotel vehicles can take visitors around the city on-demand if there are three or more riders on board and to conventions if the conventions bring more than 5,000 visitors.

Other shuttles can give rides only to customers who pre-arrange the service.

Taxicab companies were pleased with the new rules. Drivers of shuttles and limos weren't, saying taxis shouldn't be protected from competition. Shuttle drivers said they should be able to provide on-demand service.

That could happen in the future.

The council plans to pass a more sweeping ground-transportation ordinance in the fall. A portion will address service for disabled people.

Tuesday's vote moves that issue along by requiring the city's three taxi companies to offer by October at least one vehicle for the disabled.
