RESERVED LANES FOR BUSES AND CAR POOLS

ONE OF THE BASIC PROBLEMS CONFRONTING TRANSPORTATION PLANNERS IN ANY SITUATION IS HOW TO PROVIDE SUFFICIENT CAPACITY TO ACCOMMODATE TRAVEL DEMANDS. IN MANY CONGESTED FREEWAY CORRIDORS, THE SOLUTION MUST LIE IN THE CONCEPT OF ALLOCATING EXISTING ROADWAY SPACE TO ITS MOST EFFICIENT USE. AN ANALYSIS IS PRESENTED OF THE DELAY INFLICTED UPON LOW-OCCUPANCY AUTOMOBILES WHEN VARIOUS COMBINATIONS OF BUSES AND "CAR-POOL AUTOS" ARE GRANTED EXCLUSIVE USE OF ONE LANE ON A FREEWAY. THE ANALYSIS IS APPLIED TO DEMANDS OF 10,000 AND 20,000 PERSONS/HOUR (ONE-WAY) FOR THE FOUR CONDITIONS OF (1) MIXED FLOW ON ALL LANES, (2) ONE LANE RESERVED FOR BUSES ONLY, (3) LANE RESERVED FOR ALL VEHICLES WITH TWO OR MORE OCCUPANTS, AND (4) LANE RESERVED FOR ALL VEHICLES WITH THREE OR MORE OCCUPANTS. INDICATIONS ARE THAT ON HIGH-DEMAND FREEWAYS (FOUR LANES IN EACH DIRECTION), USE OF A RESERVED LANE BY BUSES AND CAR-POOLS OF THREE OR MORE PERSONS WOULD PRODUCE AVERAGE DELAYS TO LOW-OCCUPANCY AUTOS 6 TO 12 PERCENT HIGHER THAN EXPERIENCED WITH COMPLETELY MIXED FLOW. /BPR/
