| Commentary | None |
| Guideline | Toll Collection Equipment Technology Guideline 2 |
| Title | ACM Hopper/Basket Size & Location |
| Text | Circumference and height of the top of the basket should be specified to easily accommodate the majority of customers while adequately handling the remaining customers. |
| Commentary | None |

| Title | ACM Visibility |
| Text | The ACM cabinet should be finished with a bright color (other than white to retain contrast with the attached basket material) that is distinctive of any other colors used in the toll lane. |

| Title | ACM Toll Display and User Feedback |

| Guideline | Toll Collection Equipment Technology Guideline 5 |
| Title | Provisions for Accommodating Trucks in an ACM Lane |
| Text | Dual height ACMs should not be implemented in automatic lanes unless daily truck volume through the lane exceeds 25% and this solution is determined to be more economical than a preclass or VES based solution. |
| Commentary | This recommendation factors in the continued growth in ETC penetration and expansion of payment machines using bill changers and credit card proximity readers capable of handling any toll amount, affectively limiting ACMs to unattended ramp plazas. |
