In order to meet current and future traffic control needs, the system also provides extensive control monitoring, data collection, reporting, and analysis functions.
For complete user flexibility, the system provides full access of each local system intersection controller from the Remote Monitoring Station site. Full access includes the capability to upload all time settings, operation parameters, and status information, as well as the capability to download all time settings and operation parameters.
B. System Architecture. The system consists of four principal elements:
1. Local intersection controller (see 733.02)
2. Communication links
3. Traffic responsive master controller (see 733.06)
4. A Remote Monitoring Station consisting of computer equipment and software
C. Local Intersection Controllers. Furnish controller units conforming to 733.02 for the type of controller shown on the plans. Furnish a controller that has internal communication capability compatible with the type of interconnect cable shown on the plans.

740 PAVEMENT MARKING MATERIAL
740.01 General. Permanent pavement marking materials that meet the requirements of this specification and that have passed the service test required by Supplement 1047 are included on the Approved List maintained by the Office of Materials Management (OMM). OMM may retest pavement marking materials pre-qualified by a service test to determine formulation compliance to pre-qualified material and compliance with physical properties specified herein. Certified test data and samples will be furnished by the manufacturer to OMM. Failure of testing or certified test data to show formulation conforming to pre-qualified material or compliance with specified physical properties may be cause for removal of the material from the Approved List.
Ensure that the marking material is delivered in containers that are clearly marked to indicate the number of gallons (liters), weight or size of material, material density (weight per unit volume), material color, batch number or other similar manufacturer’s identification, date of production, and the company name and address.
740.02 Traffic Paint. Furnish white and yellow ready-mixed traffic paint suitable for marking various types of pavement. Ensure that the manufacturer formulates the traffic paint Type 2 in such a manner as to meet the requirements of this specification. Furnish traffic paint Type 1 pre-qualified according to Supplement 1047.
Furnish paint that is a suitable binder for glass beads, 740.09 Type A, on pavement exposed to traffic. Furnish paint that will not deteriorate in storage, within one year after date of receipt, to the extent that it cannot be readily broken up with a paddle to a smooth uniform paint capable of easy application by spray.
Furnish paint that does not bleed or discolor when sprayed on asphalt concrete surfaces.
Type 1 paint is the fast dry, water-based 100 percent acrylic type.
Type 2 paint is the fast dry, alkyd type.

Furnish pavement marking material that will be in “no tracking condition” in two minutes. The “no tracking condition” will be determined by applying the markings and beads at the specification requirements to dry pavements at a low temperature of 45F (7 C) and high temperature of 120 F (49 C). Run tests at the manufacturer’s highest and lowest recommended application humidity. The marking materials will be applied at the manufacturer’s recommended application temperature. The “no tracking” time will be determined by passing over the line with a passenger car at a speed of 25 to 35 mph (44 to 55 kmph) in a simulated passing maneuver. A line showing no visual deposition of the material to the pavement surface when viewed at a distance of 50 ft (15 m) will be considered as showing “no tracking” and conforming to this requirement for time to “no track”.
