(A)

WHEN

MECHANICAL VENTILATION SYSTEMS

TRANSPORT EXCHANGES WERE DESIGNED, IT

THE

THEY

IN

COVERED

WAS BELIEVED

WERE ADEQUATE

IN

AMELIORATING

IT WAS

FOUND THAT

THAT POLLUTION PROBLEM IN THESE INTERCHANGES. A RECENT

STUDY,

THE AIR

HOWEVER, IN VERY HIGH

VENTILATION RATES WOULD BE REQUIRED TO ENSURE THAT THE AIR QUALITY OBJECTIVES AT THE WAITING PLATFORMS

COULD

BE MET. THE REQUIRED VENTILATION RATES ARE BEYOND THE CAPACITY OF THE EXISTING SYSTEMS,

(B) THE PILOT PROJECT WILL REQUIRE $3,980,000.

18-MONTH PROJECT VENTILATION SYSTEMS

STILL

SEEKING

ΤΟ

THIS PROJECT.

IT IS AN OF STUDY THE VARIOUS DESIGNS

WE ARE FOR WAITING PLATFORMS.

THE FUNDS FOR ADMINISTRATION WILL CONSIDER APPLYING THE SUCCESSFUL INTERCHANGES. AN DESIGN TO OTHER COVERED TRANSPORT ESTIMATE OF THE TOTAL COST IS NOT AVAILABLE BECAUSE WE HAVE NOT YET DECIDED ON THE DESIGN TO BE ADOPTED.

(C)

(D)

OF THE MORE IS OPTIMISTIC THAT ONE OR GOVERNMENT DESIGNS WILL BE SATISFACTORY. THE MAIN PURPOSE OF THE TO STUDY IS TO CHOOSE THE MOST PRACTICAL OPTION AND COLLECT TECHNICAL DATA AND DETAILS ON THE COSTS OF THE DESIGN.

IN THE INTERIM, WE HAVE ADVISED TRANSPORT COMPANIES TO TURN OFF ENGINES OF IDLE VEHICLES INSIDE THE TRANSPORT INTERCHANGES. PROPERTY MANAGERS ARE ALSO ADVISED TO

THE VENTILATION OPERATE

PEAK TRAFFIC

WHENEVER WE HOPE THE ABOVE MEASURES

DURING

PRACTICABLE.

ALLEVIATE THE PROBLEM.

SYSTEMS TO

HOURS

FULL

CAPACITY

SUCH WOULD HELP
