City eyes high-tech parking

Vancouver is carefully watching two ambitious high-tech pilot projects in San Francisco and Los Angeles where on-street parking rates are varied monthly depending upon demand.Those programs, which result in vast swings in metered parking rates by so much as a single block, are the newest efforts by transportation engineers to more accurately price on-street parking to account for congestion. In some cases two adjacent blocks can vary by as much as $3 to $4 per hour. The changes are also designed to encourage alter-native forms of transportation such as mass transit, bicycling and walking.
