Narrative:

Taxi began at hangar. Taxi instructions were originally to taxi to runway 1 via taxiway B, cross runway 6, hold short of runway 1. I understood this and began to taxi. Just after I began taxiing, the controller changed the taxi instructions to, 'turn left on runway 6, hold short of runway 1.' this forced me to comply without having a chance to stop and think. As the enclosed airport diagram shows, the intersecting runway 1 comes up on an angle. The exact point to stop and hold short is not perfectly clear without a 'hold short' line. I feel that there should have been a hold short line before runway 1. Because of this, I accidentally taxied onto runway 1. The ground controller told me at that point to hold my position -- I complied. A cpr jet was told to abort takeoff on runway 1. Then I was told to turn 180 degrees and taxi back to hangar. This runway incursion resulted for 3 reasons: 1) controller changed his mind on the taxi instruction during the taxi. 2) there was no hold short line. Runway sign was in a difficult location, and runway intersects other runway at an angle. 3) the lack of a southeast taxiway forces everyone to taxi 'the long way' around the airport, causing ground congestion. I feel that future occurrences can be prevented if: 1) a second runway sign is installed on the other side of the runway. (The one on the left is difficult to see.) 2) hold short lines are painted on both sides of the runway intersection. (Too many aircraft are told to use runway 6 as a taxiway. A hold short line would clarify things.) 3) a southeast taxiway should be installed. This would alleviated much of the ground congestion, and therefore, much of confusion during taxi as well.

Title: A CPR JET IS TOLD TO ABORT ITS TKOF WHEN A C172 CFI PLT PERFORMS A RWY INCURSION ON THE ACTIVE RWY AT TEB, NJ.

Narrative: TAXI BEGAN AT HANGAR. TAXI INSTRUCTIONS WERE ORIGINALLY TO TAXI TO RWY 1 VIA TXWY B, CROSS RWY 6, HOLD SHORT OF RWY 1. I UNDERSTOOD THIS AND BEGAN TO TAXI. JUST AFTER I BEGAN TAXIING, THE CTLR CHANGED THE TAXI INSTRUCTIONS TO, 'TURN L ON RWY 6, HOLD SHORT OF RWY 1.' THIS FORCED ME TO COMPLY WITHOUT HAVING A CHANCE TO STOP AND THINK. AS THE ENCLOSED ARPT DIAGRAM SHOWS, THE INTERSECTING RWY 1 COMES UP ON AN ANGLE. THE EXACT POINT TO STOP AND HOLD SHORT IS NOT PERFECTLY CLR WITHOUT A 'HOLD SHORT' LINE. I FEEL THAT THERE SHOULD HAVE BEEN A HOLD SHORT LINE BEFORE RWY 1. BECAUSE OF THIS, I ACCIDENTALLY TAXIED ONTO RWY 1. THE GND CTLR TOLD ME AT THAT POINT TO HOLD MY POS -- I COMPLIED. A CPR JET WAS TOLD TO ABORT TKOF ON RWY 1. THEN I WAS TOLD TO TURN 180 DEGS AND TAXI BACK TO HANGAR. THIS RWY INCURSION RESULTED FOR 3 REASONS: 1) CTLR CHANGED HIS MIND ON THE TAXI INSTRUCTION DURING THE TAXI. 2) THERE WAS NO HOLD SHORT LINE. RWY SIGN WAS IN A DIFFICULT LOCATION, AND RWY INTERSECTS OTHER RWY AT AN ANGLE. 3) THE LACK OF A SE TXWY FORCES EVERYONE TO TAXI 'THE LONG WAY' AROUND THE ARPT, CAUSING GND CONGESTION. I FEEL THAT FUTURE OCCURRENCES CAN BE PREVENTED IF: 1) A SECOND RWY SIGN IS INSTALLED ON THE OTHER SIDE OF THE RWY. (THE ONE ON THE L IS DIFFICULT TO SEE.) 2) HOLD SHORT LINES ARE PAINTED ON BOTH SIDES OF THE RWY INTXN. (TOO MANY ACFT ARE TOLD TO USE RWY 6 AS A TXWY. A HOLD SHORT LINE WOULD CLARIFY THINGS.) 3) A SE TXWY SHOULD BE INSTALLED. THIS WOULD ALLEVIATED MUCH OF THE GND CONGESTION, AND THEREFORE, MUCH OF CONFUSION DURING TAXI AS WELL.
