Last mile connectivity Mediums for transit oriented development along pipeline

Cable car as urban transport Contextually suitable mode since

Skywalks • Area to cover is large 2.2km

Cycling tracks/pathways • Does not cater to mass transit.

• Requires continuous land area

Trams • Requires tracks on land, hence restricted use.

Cable car • Small footprint • Ariel transport • Most suited for context.

• • • • • •

Pipeline running on ground.

Narrow road conditions.

Residential area.

Small footprint for station and pylons.

Station can be integrated with many activities.

Opportunity to develop the pipeline path area.

• • • • • •

Traffic free transit Frequency of transit is constant Pollution free Fast Cheap Negligible noise

Most suited type of aerial transit

Urbane scenario Belt of low and medium income group.

Connects the metrocable to the main metroline running through the city.

Medium capacity transit system.

Narrow streets condition.

High density population.

Residential area.

Stations used as points of recreation and community space.

Extending the reach within the city.

Standards for design Line length: 3.275km Number of stations : 5.

Type of aerial transport: monocable detachable gondola (MDG).

Capacity per car : 8-10 persons per car.

Number of cars - phase 1- 6 cars between two adjacent stations.

Total number of cars : 16 cars Speed : 6 m/s.

Average Time of travel between two adjacent stations : 2.30min.

Total time of travel between terminal stations : 16min.

Waiting period at station : 1min 58sec.

Capacity of Transit : 540 PPHPD

Size of the car 2.0x1.8

Why MDG? • •

Efficient for low-medium capacity needs.

As the investment is quite low compared to other technologies, MDGs are excellent “starter” systems for cities intrigued by the technology. They can act alone as mid-capacity main lines, or function as feeder lines to other higher order transit technologies such as subways.

Type of transit : Shuttle type. (in continuous movement).

Image showing the movement of six cars, three in each direction between two adjacent stations.

Calculations.

Speed :6m/s (21.6 km/h) Hence for 640m -2.52min.

575m- 2.4min.

960m- 4.2min.

1100m-5.05min.

For 3.275km – 14.57min + (30x3)= 16.27min. (30s consumed at intermediate station) Number of cars per direction

Phase 1: 3 cars per direction • can transport 100 Persons per hour between terminal stations.

• can transport 457 Persons per hour between adjacent stations.

Waiting period at each station will be 2min.

Phase 2: 4 cars per direction • can transport 132 Persons per hour between terminal stations.

• can transport 610 Persons per hour between adjacent stations.

Waiting period at each station will be 1.28min.

In 20 years when the transit system is in full fledge use, the programme can look at having 7 cars per direction, transporting 464 persons between terminal stations and 2135 persons between intermediate station.

The line can also be extended towards banashankari 6th stage where most engineering colleges are located.

Station design

Tower design

Rooms required: 1. Gondola garage - required at intermediate stations to house the cars when not used.

2. Propulsion room- room for the engine.

3. Surveillance room- to keep track of the effective movement of cable cars 4. Ticket counter- to pay and collect tickets for transit.

5. Waiting space- wait for the gondola.

• Type of tower : cylindrical.

• Size of pedestal : 2.5x2.5 • Each tower supports a pair of cable car ropes.

• Dia. Of tower: 1.25m.
