Frequently asked

Glossary

1

Asset management

A data-driven approach to keeping pavements, bridges, signs and other road assets at a target service level across their life cycle. It links condition surveys, budget planning and maintenance priorities so agencies can compare investment options.

2

Automatic traffic signal control

Software and field controllers that adjust signal timings in response to detected traffic demand. It is used to reduce delay on arterials and to coordinate junctions around event traffic and incident diversions.

3

BIM for infrastructure

Building information modelling applied to roads, bridges and drainage, using a shared digital model through design, construction and handover. It supports clash detection, quantity take-off and as-built records.

4

Complete Streets

A road design approach that plans for all users, including pedestrians, cyclists, transit riders and drivers. Projects often combine lane reallocation, crossings, sidewalks and speed management.

5

Connected and automated mobility

Vehicle-to-everything (V2X) communication and automated driving systems that rely on road-side infrastructure, digital maps and reliable connectivity. Road operators use it to plan signage, lane markings, charging and data links.

6

Curb management

The active allocation of kerb space for loading, parking, transit stops, micromobility and outdoor dining. Digital permits and sensors help cities manage competing demands and enforce access rules.

7

Intelligent transportation systems (ITS)

The integration of sensors, communications and control software to manage traffic, incidents, tolling and traveller information. ITS includes detection, variable message signs, traffic management centres and connected vehicle services.

8

Life-cycle cost analysis

A method that compares initial construction cost with future maintenance, rehabilitation and user costs over an asset's service life. It helps agencies justify pavement type, materials and preservation strategies.

9

Managed lanes

Lanes whose access or price is actively managed to keep traffic flowing, often through tolls, occupancy rules or dynamic pricing. They require enforcement, signage and back-office account systems.

10

Pavement management system (PMS)

A database and decision tool that stores pavement condition, traffic and treatment history. It ranks candidate projects and forecasts budget needs across a road network.

11

Pavement preservation

Timely, lower-cost treatments such as crack sealing, seal coats, micro-surfacing and thin overlays that extend pavement life before major reconstruction is needed. Preservation programmes depend on condition data and treatment timing.

12

Road safety audit (RSA)

An independent review of a road project or existing route to identify safety risks for all users. Findings are ranked by crash likelihood and severity so designers can change layouts, signs or markings.

13

Road weather information system (RWIS)

Road-side sensors and weather feeds that report pavement temperature, precipitation, visibility and salt concentration. Operators use RWIS data to trigger treatment, closures and traveller warnings.

14

Tolling and congestion pricing

Charging road users for access to a facility or for travel during congested periods. Systems combine tag readers, cameras, classification and payment enforcement, and are often paired with managed lanes.

15

Vision Zero

A road safety policy goal of eliminating traffic deaths and serious injuries through safe speeds, safe roads, safe vehicles and safe road users. It is commonly applied through audits, speed management and post-crash analysis.

16

Work zone traffic control

Temporary traffic management around construction and maintenance sites, including signs, barriers, lane closures and queue protection. Safe work zones require a traffic control plan, inspection and crash reporting.

17

Crash modification factor (CMF)

A statistical estimate of how much a treatment changes crash frequency or severity at a site. CMFs help agencies compare countermeasures such as roundabouts, rumble strips or improved lighting.

18

Mobility as a Service (MaaS)

A model that bundles public transport, bike share, ride-hail and parking into one journey-planning and payment service. Road authorities use it to influence mode choice and reduce single-occupancy travel.

19

Geosynthetic reinforcement

Polymer grids, geotextiles or geocells placed in pavement layers or embankments to improve strength and reduce deformation. They are selected using soil conditions, traffic loading and drainage design.

20

Infrastructure resilience

The capacity of road networks to withstand and recover from floods, heat, wildfire, earthquakes and other shocks. Resilience planning links asset data, climate risk, emergency routes and recovery funding.
