1. Transportation agencies across the country are looking for ways to provide safe, efficient, and reliable travel across modes and jurisdictions under increasingly constrained fiscal environments.Please, continue.

The public, business leaders, and elected officials want reliable goods movement, timely and accurate traveler information, safe and quick incident clearance, and greater options in transportation modes, routes, and services. To address the need for mobility, safety, and security, many transportation agencies have integrated management and operations into their set of solutions.

2. Traffic capacity and shoulder/pullout areas are often restricted in work zones.Please, continue.

Traffic capacity and shoulder/pullout areas are often restricted in work zones. Prompt detection and clearance of traffic incidents in work zones can help reduce secondary crashes and delay. Preparing a work zone TIM plan and using strategies that improve detection, verification, response, and clearance of crashes, mechanical failures, and other incidents in work zones and on detour routes can benefit safety and mobility. Specific strategies are identified in FHWA's, Traffic Incident Management in Construction and Maintenance Work Zones

3. Write the formula for calculating the number of full-time workers

(2.12)

where

T – total annual working hours;

Ф_Ш –annual fund of time of full-time workers, hours.

Value of Ф_Т and Ф_Ш depends on working conditions:

• For harmful working conditions annual fund of time of workers are:

Ф_Т = 1780 hours and Ф_Ш= 1560 hours (35 hours per week)

• For non-harmful working conditions annual fund of time of workers are:

Ф_Т = 2020 hours and Ф_Ш= 1770 hours (40 hours per week)

Examination ticket № 14

1. Management and operations strategies can often improve transportation system performance significantly and be deployed more quickly and more cost-effectively than traditional capacity expansion projects.Please, continue.

Management and operations (M&O) strategies focus on getting the most efficient and safest use out of existing or planned infrastructure through activities such as traffic incident management, traveler information dissemination, traffic signal coordination, and work zone management. 

2. The transportation facility should be designed with construction and post-construction maintenance of traffic activities in mind.Please, continue.

The inclusion of work zone management and operations should be identified during needs development and preliminary engineering so that strategies can be implemented prior to the start of major construction activities if needed. In addition, the transportation facility should be designed with construction and post-construction maintenance of traffic activities in mind. Designers must consider how the facility will be constructed in a manner that provides a safe working environment and minimizes the impact on the operation of the facility. This may require consideration of construction methods and staging.

3. Write the formula for calculating the number of auxiliary workers

(2.13)

and

(2.14)

where

Т_ВСП –annual amount of annual auxiliary working hours;

Ф_Ш – annual fund of time of full-time workers, hours.
