Fig 10.6 : Typical layout of multi storeyed parkingA simple design of the bus bay directly abutting the footway is given in Fig . 10.7

Fig 10.7 Lay out of bus bay abutting footway

Where L 1 = 12 m Minimum for Congested locations of single bus, add 12 m for additional bus= 15 m desirable for single bus, add 15 m for every additional bus

W = 3 m minimum for congested areas

= 3.5 m desirable

L 2 = 6 W minimum for congested areas= 8 W desirable

A layout of the bus-bay when a separate lane is provided for slow moving vehicles is given in Fig 10.8

Width W of island depends on number of passengers expected to be present at a particular t ime for loading andunloading purposes.

The width may be increased by 0.5 m for 25 passengers thereafter.

10.5 Truck Terminals:

The indiscriminate parking of trucks in the streets and upon spaces of the towns and cities has many adverseeffects. The foremost is the degradation of the environment and the increased hazards to traffic. Security of thegoods contained in the parked vehicles can also be a serious problem. The needs of the truck drivers who have

often to drive for long hours and consequently need rest, toilet facilities and food deserve careful consideration.The right approach is to provide well designed truck terminals at the fringes of the cities.

The truck terminals should be located on important arterial routes and at the confluence of a number of suchroutes. They should be close to major generators of commercial activity.

The length of truck berths depends upon the type of trucks to be handled. Truck trailer combinations obviouslyneed longer lengths than single unit trucks. For single unit trucks a space of 3.75 m * 7.5 m per vehicle isadequate. For truck tailer combinations lengths up to 15 m may be needed. The width of the loading platformsshould be 3.5 to 4.5 m. About 600- 750 trucks can be accommodated in a parking area of one hectare. The arearequired for the entrance forecourt, hotel, resting place and ancillary facilities ( weigh bridge, fuelling facilities,

workshop) is in addition to the parking area requirement.

Typical layout of a truck terminal is given in Fig 10.9 below.
