This document discusses road maintenance reform in the Republic of Moldova. It provides an overview of asset management principles and the use of the HDM-4 tool for road asset management, which can be used for planning, programming, project analysis, and other functions. The document also covers road deterioration concepts and models in HDM-4, which take into account factors like traffic volume, climate, and maintenance policies. Pavement classification systems and the modeling framework for different pavement types are also summarized.

Ppp for public bicycle sharing and parking management in kharghar navi mumbai...Avinash Shabade
PPP for Kharghar Node (A Nodal Area in Navi Mumbai)
Navi Mumbai is one of the largest planned cities in the world with 344 Sq. km. a conglomerate of 14 nodes, these nodes are independent cities & Kharghar is one of them. The infrastructure problem faced by this node is
1. Efficient local Public transport & feeder transport
2. Illegal on street parking
To address this issue for the local development authority is difficult hence a combined, one of its kind PPP model for Public bicycle sharing and on street parking management is proposed.
Title: Level of Service F for Grade A Streets
Track: Prosper
Format: 90 minute panel
Abstract: Relying solely on Level of Service criteria for street design, which evaluates vehicle congestion, leads to poor outcomes on many of our roadways. LOS F, far from a failure, creates opportunities to reallocate roadway space for more livable street designs. In this session, learn about projects in Cambridge and San Francisco that overcame opposition and generated community support in prioritizing better bicycling and walking over vehicle capacity during the peak hour of travel.

Cracking the Workplace Discipline Code Main.pptxWorkforce Group
Cultivating and maintaining discipline within teams is a critical differentiator for successful organisations.
Forward-thinking leaders and business managers understand the impact that discipline has on organisational success. A disciplined workforce operates with clarity, focus, and a shared understanding of expectations, ultimately driving better results, optimising productivity, and facilitating seamless collaboration.
Although discipline is not a one-size-fits-all approach, it can help create a work environment that encourages personal growth and accountability rather than solely relying on punitive measures.
In this deck, you will learn the significance of workplace discipline for organisational success. You’ll also learn
• Four (4) workplace discipline methods you should consider
• The best and most practical approach to implementing workplace discipline.
• Three (3) key tips to maintain a disciplined workplace.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.

Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.

For each pavement type:
a generic model applies to describes the pavement deterioration
After maintenance treatments:
the generic pavement type can change
Pavement Strength:
is characterized by “Adjusted Structural Number” (SNP)
The SNP applies a weighting factor (prevent over-prediction of
pavement strength with increase of depth)
Construction Quality:
Construction Defect Indicators: CDS (surface) and CDB (Base)
CDS: 0.5-1,5 from brittle to soft depending on Binder content
CDB: 0-1,5, No defects or several defects

Net Present Value (NPV)
The higher NPV the higher Benefit
Without budget constrain, shall the alternative with highest NPV be chosen
Comments
Larger investment tends to have higher NPV
NPV is proportional to the project cost if IRR is the same
Economic Internal Rate of Return (IRR)
IRR = the discounted rate at which the NPV is equal to 0
Gives no indications of the size of costs or benefits of an investment
Acts as a guide to the profitability of the investment
The higher the better
If IRR > Discount rate, the investment is said to be economically justified

Benefit Cost Ration (BCR)
Ratio indicating the profitability of one option relative to base option

First Year Benefit (FYB)
FYB is defined as the ratio in present of the net benefit realized in
the first year after construction
Rough guide to project timing
If FYB > discounted rate, the project should go ahead
If FYB < discounted rate the project should be delayed until it satisfies

Editor's Notes
While there is no one method that will fit every situation or agency, all asset management structures have certain basic elements in their approach. These include:
-- Setting Goals and Objectives
-- Collecting appropriate data
-- Calculating and analyzing deterioration rates
-- Setting performance standards and measuring progress
-- Use of life-cycle cost analyses
-- Developing investment strategies
-- Selecting programs and projects consistent with the selected strategy
-- Monitoring the results and making adjustments if necessary.

So what is driving the move toward asset management?
Our transportation systems are mature ones with many roads and bridges built 30 to 40 years ago. Consequently, we are facing a period of re-investing in existing facilities rather than building new ones. This has been reflected in federal funding where they are moving from strictly capital funding to more flexible funding for preventive maintenance.
Because of the reports I mentioned earlier, the general public expects us to spend their money wisely and efficiently. And they are demanding greater accountability.
We have seen a new breed of leaders coming into transportation. Rather than coming from the engineering field, many of today’s leaders are coming from the political arena or business community. And they are bringing with them a sensitivity to constituents and management concepts and principles that worked in business.
Fourth, there have been vast improvements in computers and technology that make it possible to do things today that we could never do before.
Finally, there is the well-recognized relationship between an efficient, productive transportation system and economic growth.
