Introduction

Transportation planning - purposes

 Early planning principles, provide connectivity

 Then, to provide capacity within reasonably safe standards

 Then, provide continued services

 Still later, introduce sustainability concept

 In general, the purpose of transportation planning has been to ensure, efficient, equitable
and sustainable performance of transportation systems

Introduction

Transportation planning – paradigms

 Until the early 90’s: predict and provide

 Produce demand forecasts

 Find engineering solutions that serve the demand and satisfy the objectives

 However, it became evident

 Increasing and improving quality of supply tend to stimulate growth of demand


(traffic induction)

 Demand can’t always be satisfied without

 Unacceptable costs of space occupation in urban areas

 Unacceptable costs of environmental aggressions overall

Introduction

Transportation planning – paradigms

 New paradigm: Aim and manage

 Aim at the level of performance and quality wished for the network (or system)

 Manage the evolution of the system in such a way that those targets will be met

 Instead of doing forecasts (free growth of demand), include constraints in the analysis
and find

 Provide mobility levels that allow efficient support of social and economic activities

 Influence choices of citizens and companies about the mobility of persons and freight in such a way
that the negative impacts of that mobility are within acceptable limits

 Infrastructure and technology (Engineers)

 Legislation and regulation (Legislators)

 Prices, taxes and charges (Economists)

Introduction

Transportation planning – institutional framework

 1950s

 Modernism

 Dominated by engineering principles

 Public support highly sought but not at the expense of traffic efficiency, increased costs and delays

 Transportation planning = quantifiable process

 1960s

 Post- modernism

 Participation on planning and vice versa

 Technical activity serving conflicting positions

Introduction

Transportation planning – conceptual models of decision making

Satisficing Approach

 Assumed behavior

 Select first alternative to meet minimal acceptability level

 Characteristics

 Impossibility of generating and comparing all feasible alternatives

 Sequential discovery of alternatives

 Goal oriented, but adaptive

 Constrained rationality

 Planning implications

 Still data-intensive, but for fewer alternatives (and criteria)

Introduction

Transportation planning – conceptual models of decision making

Incremental Approach

 Assumed behavior

 Problem avoiding (instead of objective-obtaining)


 Decisions based on marginal differences
 Characteristics

 Limited number of alternatives


 Limited communication among decision-makers
 Focus on marginal differences
 No single solution, conceptual problem response
 Remedial, not long-term driven
 Planning implications

 Information requirements limited (minimal alternatives, marginal differences)

Organizational process Approach

 Assumed behavior

 Organizational structures, communication channels and standard operating


procedures drive decisions

 Characteristics

 Organizational goals drive choice process


 Operating routines define range of alternatives
 Organizational propose alternatives
 Planning implications

 Need to understand:

• Organizational goals and objectives


• Limits to implementation capabilities

Introduction

Transportation planning – conceptual models of decision making

Political bargaining Approach

 Assumed behavior

 Pluralistic process of conflict and bargaining

 Characteristics

 Large number of actors with diverse goals, values and interests


 Outcomes represent aspect of problem on which agreement can be reached
 Controversial decisions are postponed
 Planning implications

 Broad role for planners


 Flexibility may require new information as negotiations produce new alternatives
 Expect competing issues to arise
 Full information and transparency required

 Determine weather a project under consideration is worth investment at all

 Evaluate alternative strategies

 Stage Vs full construction

 Flexible Vs Rigid pavement

 Design standards

 Alternative policy options on axle loads

Introduction

Running a business

 Use of a production function

 The production function predicts what resources are needed to provide different levels of
output

 Given prices of the inputs, we can find the most efficient (i.e. minimum cost) way to
produce a given level of output

Introduction

Running a business

 Production function

 Technology: method of turning inputs (including raw materials, labor, capital, such as
vehicles, drivers, terminals) into outputs (such as trips)

 Production function: description of the technology of the firm, maximum output produced
from given inputs

Multicriteria Decision Analysis

 A point of view is whatever aspect, within a certain context, that the decision makers
consider relevant to evaluate the attractiveness of the actions/alternatives

 A criterion is an instrument that allows the evaluation of actions/alternatives according


to particular point of view

 A pro-active orientation of the decision maker (what are the “objectives” to be


achieved?) – subjective elements

 An analytical re-active orientation (what are the characteristics of the


alternatives that affect their attractiveness?) – objective elements

 A contract is legally binding exchange of promises or agreement between parties that the
law will enforce

 Breach of contract is recognized by the law and remedies can be provided

Introduction

Project management and contracts – contracts

Classification of a project delivery methods

 When the state retains full responsibility for financing

 DBB: Design – Bid – Build: full separation between design and building stages, with
independent bids and contracts for each stage. State in charge of all stages after initial
construction

 DB: Design – Build: design and build are combined in a single contract, based on a
preliminary design (or even only functional requirements) supplied by the state. Calls
for greater innovation in construction methods, but increases vulnerability of state if it
changes its requirements after selection of the provider. State in charge of all stages
initial construction

 DBO: Design – Build – Operate: extension of DB in which the private provider also
retains responsibility for O&M. Early stages financed directly by state, O&M possibly by
user charges, but commercial risk stays with state

Introduction

Project management and contracts – contracts

Classification of a project delivery methods

 Provider in charge of financing – sometimes PPP

 DBFO ~DBOT: Design – Build– Finance – Operate: extension of DBO in which the
private provider takes the responsibility of obtaining the funds needed to deliver the
project and associated services, and gets his return largely from user charges, thus
assuming commercial risk

 In a PPP the public part also frequently bears part of the financial costs (or risks)

 Sometimes by taking part of the shares of the concessionaire, sometimes by


bringing some assets into the contract but staying out of that society

Introduction

Quality assurance and control

 Highly dependent on the type of contract

 Continuous maintenance programs

 There needs to be strong institutions that continuously inspect,


assesses and maintain state funded transport infrastructures
