As of March 2020 The Tranportation Technology Transfer Service Payment no longer accepts check payments. Credit card is the preferred payment method. Your payment must be received within 5 business days of your registration. If your registration payment is not received by then, you will not be guaranteed registration for the conference.
If you cancel your registration more than 72 hours before the conference, your registration fee will be refunded, less a $50 processing fee. If you do not cancel before the 72 hour deadline your registration fee will not be refunded. No-shows will not have their registration fee refunded.
