TRA-4 COMMUTING MASS TRANSPORT

 

Technical Clarification

Clarification for stops at the end of a route

Technical Clarification Number
TRA4-T-OB1-1090

Guidance
2015-12-23

The Commuting Mass Transport Guide states that, "Only services which arrive at the stop can be used to calculate the average interval for the morning peak period; conversely only services that depart from the stop can be used to calculate the afternoon peak period." In addition, "A route with services for two directions (e.g. northbound and southbound) where one direction only has services in the morning and the other direction only has services in the afternoon is considered one route."

People can only arrive from one direction in the morning then depart in the opposite direction to go home in the afternoon. There is mass transit service provided in only one map direction from the project site.

Clarification: A route in which the closest stop to the project site is at the end of the route (termination or turn-around point) is considered one route, even if services are provided in both directions all day long.

Credit Interpretation Request

Alternative documentation for contract requirements

Credit Interpretation Request Number
TRA4-C-OB1-629

Ruling
2013-01-13

The Credit Interpretation Request (CIR) seeking approval to submit alternative documentation in lieu of the contracts for the Tra-4 Commuting mass transport is conditionally approved.

The approval of this CIR is thus contingent on the project team submitting a sample contract and a signed letter of confirmation from the relevant contracting body (i.e. Relevant Precinct Property Owners’ Association body representative) with a tabulated list of all the contracted services and routes. The letter should also state that signed contracts exist for all service providers included in the table and that the signed sample contract provided is an example of a standard contract that exists between the contracting body and each individual service provider listed. Additionally, extracts from each contract showing the signatures (i.e. page 14 of the sample contract) of both representatives must be submitted. Please note that the other documentation requirements stipulated in the Green Star SA – Office v1 Technical Manual must still be adhered to.

Future Services for MyCiti bus services in Cape Town

Credit Interpretation Request Number
TRA4-T-OB1-0580

Ruling
2012-10-01

Future MyCiti bus services may be included in calculations for Tra-4 Commuting Mass Transport. Where bus services are included for credit (as mainline, feeder or connecting services) but not operational at the time of the Green Star SA submission.

The most recent schedules, maps and other relevant information from the MyCiti website may be used and is acceptable evidence towards your Green Star SA submission.

For future routes and information not available on the MyCiti website, a confirmation from the relevant transport authority of the planned service frequency, hours of operation and route applicable to the project site is required.

Do note that all other documentation requirements/TC’s and CIR’s remain unchanged.

Credit Interpretation Request

Interpolating stop-times from timetables

Credit Interpretation Request Number
TRA4-T-OB1-0313

Ruling
2011-08-23

Where timetables available for a public transport route do not show stop-times for all stops along the route, interpolated times may be used. The following methodology should be used for interpolating the required stop-time:

Stop-time = [Time at start point (or nearest published stop-time before required stop)] + [Average Speed x distance travelled from start point (or nearest published stop-time before required stop)].

Where:

Average Speed = d/t

d = Distance travelled between start and finish of route (or time between closest published time before required stop and closest published time after required stop)

t = Time between start and finish times of route (or time between closest published time before required stop and closest published time after required stop).

Credit Interpretation Request

Bus schedule documentation

Credit Interpretation Request Number
TRA4-C-OB1-0044

Ruling
2009-09-04

The Credit Interpretation Request (CIR) seeking approval of survey results in place of timetables for bus services is approved. For bus services, projects may submit either extract(s) from current timetables less than one year old from the date of Green Star SA submission (revision from Technical Manual, issued via Technical Manual Errata), survey results of observed bus operations during peak periods, or Current Public Transport Record (CPTR) data collected less than one year prior to the date of Green Star SA submission.

 

Credit Interpretation Request

Service interval calculation

Credit Interpretation Request Number
TRA4-C-OB1-0032

Ruling
2009-03-31

The Credit Interpretation Request (CIR) seeking approval for an alternative calculation methodology for Average Service Frequency is approved. Projects may either use the calculation methodology defined in the Green Star SA - Office v1 Technical Manual or use the following formula: Average Service Frequency = 120 minutes / (actual number of services in the peak 2 hour window).

 

Technical Clarification

Peak periods

Technical Clarification Number
TRA4-T-OB1-0026

Guidance
2009-03-26

For peak travel hours to be used in determining the frequency of service, projects are permitted to select any two-hour window between 6:30 and 9:30 for the morning peak period and any two hour period between 15:30 and 18:30 for the afternoon peak period. The same two hour windows must be used for all transit modes.

 

Technical Clarification

Private buses

Technical Clarification Number
TRA4-T-OB1-0022

Guidance
2009-02-06

Private bus transport systems with established routes and timetables equivalent to public transport may be included in the calculations for Tra-4 Commuting Mass Transport contingent upon the project’s ability to demonstrate that the future operation of these services is as certain as public transport (i.e. demonstrates alternative but equivalent compliance in respect to longevity, publicity, etc.). Please enter the number and frequency of services into the Public Transport Calculator and provide the evidence stipulated in the Documentation Requirements.

 

Technical Clarification

Future services

Technical Clarification Number
TRA4-T-OB1-0008

Guidance
2009-02-05

Future public transport services may be included in calculations for Tra-4 Commuting Mass Transport. Where train, bus, midibus or taxi services are included for credit (as mainline, feeder or connecting services) but not operational at the time of the Green Star SA submission, the following documentation must be provided:

- Proof of a contract signed by the relevant transport authority and the service provider, and the planned service frequency, hours of operation and route; and
- Proof of an undertaking to have the necessary transport stops constructed, whether on a public road or the development site.
