| GENERAL NOTES | |||||||||||||||||||||
| SUMMARY OF XSF FLAGS | |||||||||||||||||||||
| (Communications Operation of XSF flags is required) | |||||||||||||||||||||
| XSF1 | - | Allows for late introduction of P1 in AØ (Masterlink only). | |||||||||||||||||||
| XSF2 | - | Allows for late introduction of P2 in AØ (Masterlink only). | |||||||||||||||||||
| XSF3 | - | Allows for automatic introduction of P1 & P2. | |||||||||||||||||||
| XSF4 | - | Allows for automatic introduction of P3 & P4. | |||||||||||||||||||
| XSF5 | - | Selects special maximum for SG5 in EØ via Special Purpose Timesetting No. 9. | |||||||||||||||||||
| XSF6 | - | Selects special maximum for SG6 in EØ via Special Purpose Timesetting No. 10. | |||||||||||||||||||
| XSF7 | - | Not use. | |||||||||||||||||||
| XSF8 | - | Not use. | |||||||||||||||||||
| XSF9 | - | Allows detector 19 to extend CØ. | |||||||||||||||||||
| GENERAL OPERATION | |||||||||||||||||||||
| · Use AØ yellow for EØ yellow if transitioning from E2Ø or E3Ø to phases other than AØ. | |||||||||||||||||||||
| · Use BØ yellow for DØ yellow if transitioning from DØ -> CØ. | |||||||||||||||||||||
| · Use CØ yellow for BØ yellow if transitioning from BØ to phases other than CØ. | |||||||||||||||||||||
| · Use BØ special all red if transitioning from BØ -> EØ or BØ -> AØ. | |||||||||||||||||||||
| · Use DØ special all red if transitioning from DØ -> CØ. | |||||||||||||||||||||
| SIGNAL GROUP OPERATION | |||||||||||||||||||||
| SIGNAL GROUP 5 | |||||||||||||||||||||
| SG5 is controlled by Special Movement Timer No.1 within EØ. EØ All Red Timesetting is substituted for Special Movement Time No. 1. | |||||||||||||||||||||
| XSF5 is used to set the maximum time for SG5 in EØ. The maximum time is accessible in Special Purpose Timesetting No. 9. SG5 will be forced off after a period equal to the EØ minimum green plus this special maximum. | |||||||||||||||||||||
| SIGNAL GROUP 6 | |||||||||||||||||||||
| SG6 is controlled by Special Movement Timer No.2 within EØ. EØ All Red Timesetting is substituted for Special Movement Time No. 2. | |||||||||||||||||||||
| XSF6 is used to set the maximum time for SG6 in EØ. The maximum time is accessible in Special Purpose Timesetting No. 10. SG6 will be forced off after a period equal to the EØ minimum green plus this special maximum. | |||||||||||||||||||||
| PEDESTRIAN GROUP OPERATION | |||||||||||||||||||||
| Pedestrian 1 | |||||||||||||||||||||
| · P1 calls AØ. | |||||||||||||||||||||
| · P1 can introduce anytime in E2Ø & at the start of AØ and can overlap from E2Ø -> AØ. | |||||||||||||||||||||
| · P1 can introduce anytime in AØ if XSF1 is set (Masterlink only). | |||||||||||||||||||||
| · P1 auto introduces at the start of SG1 green if XSF3 is set. | |||||||||||||||||||||
| Pedestrian 2 | |||||||||||||||||||||
| · P2 calls AØ. | |||||||||||||||||||||
| P2 can introduce anytime in E3Ø & at the start of AØ and can overlap from E3Ø -> AØ. | |||||||||||||||||||||
| · P2 can introduce anytime in AØ if XSF2 is set (Masterlink only). | |||||||||||||||||||||
| · P2 auto introduces at the start of SG2 green if XSF3 is set. | |||||||||||||||||||||
| Pedestrian 3 | |||||||||||||||||||||
| · P3 calls CØ. | |||||||||||||||||||||
| P3 can introduce anytime in BØ & at the start of CØ and can overlap from BØ -> CØ. | |||||||||||||||||||||
| · P3 auto introduces at the start of SG3 green if XSF4 is set. | |||||||||||||||||||||
| Pedestrian 4 | |||||||||||||||||||||
| · P4 calls CØ. | |||||||||||||||||||||
| P4 can introduce at the start of CØ and can clearance overlap from CØ -> DØ. | |||||||||||||||||||||
| · P4 auto introduces at the start of SG4 green if XSF4 is set. | |||||||||||||||||||||
| DETECTOR OPERATION | |||||||||||||||||||||
| Detector 19 | |||||||||||||||||||||
| Detector 19 extends CØ when XSF9 is set. | |||||||||||||||||||||
| OPERATION OF ADVANCED WARNING SIGN | |||||||||||||||||||||
| The Advance Warning Sign is controlled by Wait State 7 (WS7) and Special Output 1 (SO1). | |||||||||||||||||||||
| Wait State 7 or Special Output 1 controls the operation of two flashing “Prepare to Stop” signs. | |||||||||||||||||||||
| Wait State 7 and Special Output 1 are switched on at the start of AØ ECO if going AØ->BØ,AØ->CØ, AØ-> DØ, AØ->E1Ø or AØ->E3Ø. | |||||||||||||||||||||
| Wait State 7 and Special Output 1 stay on until SG1 goes green in AØ or E2Ø. | |||||||||||||||||||||
| Calculation of Extra Time Period | |||||||||||||||||||||
| Extra Time | = | Time to travel from Sign to Stopline | |||||||||||||||||||
| - Time to travel from Nominal Stopping Distance to the Stopline | |||||||||||||||||||||
| + | Reaction Time (including time to travel the viewing distance) | ||||||||||||||||||||
| = | { 132 / [(60 x 1000) / 3600] } – 4 (yellow time) +2 | ||||||||||||||||||||
| = | 5.9 seconds | ||||||||||||||||||||
| Use 6 seconds | |||||||||||||||||||||
