With the exception of a centrally managed Intelligent Transport System (ITS), which would require a city-wide infrastructural commitment beyond the scope of this masterplan, all of the measures discussed herein are integral to our plan and have been evaluated for cost impact and feasibility. Please see our full traffic report, to be delivered May 13, for a more detailed description of our plan and analysis. The main concept of the traffic plan was inspired from the direct observation of traffic patterns occuring during events at the Miami Beach Convention Center. Currently traffic from the the Julia Tuttle and Mac Arthur Cause- ways routes along Alton Road and then on 17th Street in order to reach both the parking facilities and drop-off kerbs next to the Halls. The current orientation of the building and the existing distribution of parking avail- ability in the area conveys the idea that 17th street is the more convenient route to access the MBCC. However, despite the intense traffic on 17th street, it is common experience, also supported by quatitative measurements of traffic flows, that north of the Convention Center Dade Boulevard operates instead under capacity. Circulation Plan - Cars The main proposed arrangement of traffic takes advan- tage of this opportunity, reverting the current paradigm and proposing the main entrance for the vehicular flows from the north of the site branching off Dade Boulevard. This reorientation was made possible through an inte- grated design approach between traffic engineers and masterplanner: the former optimizing the traffic lights in the area, along Dade Boulevard especially, and exploit- ing the existing residual capacity, the latter by allowing in the masterplan such distribution of flows. With respect to the circulation plan, the key benefits of the chosen approach are: • the closure of Convention Center Drive between 17th and 18th street in order to inhibit through traffic, con- verting the space into a shared surface and reserving the street for MBCC operation traffic only; • the creation of dedicated off-street facilities for drop- off and pick-up for both private cars and buses; • the creation of a pedestrian exclusive area on the southern side, where flows from the drop-offs, the public transport stops and the adjacent cultural ven- ues gather and engage with the MBCC to the north and Lincoln Rd to the south. • the creation of an internal circulation loop that enables valet service to function effectively without impacting on the operation of adjacent roads; • a private exclusive access for both the hotel and the residential program; • a flexible arrangement of the internal circuit that allows the use of Convention Center Drive as an outdoor exhibition space. • Parking structures for the MBCC and the Hotel are provided at the north and the south of the exhibi- tion and meeting space with 1,388 and 500 spaces respectively. Most of the self parking will be located in the north facility which can be accessed by Con- vention Center Drive and Washington Av., as shown below. Additional parking space remains within the 17th Street parking garage. The residential area on the east side of Meridian Av- enue is served by a 503 spaces parking lot accessed via Meridan Avenue. Alternatively, private cars using valet service will access the kerbs located at the south- ern edge of Convention Center Drive as well as on 18th street directly adjacent to the south meeting rooms. Traffic heading to the hotel will route in a counter-clock- wise fashion around a landscaped berm to reach the drop-off kerb. Afterwards, vehicles will be valeted to the parking below the hotel lobby through a roundabout and a ramp accessible from beneath the berm. The propos ed layout also allows self-parking, avoiding drop-off when necessary. Finally, the berm clearance, the roundabout radii and the ramp slope are designed to allow goods vehicles access into the basement loading facility servicing the hotel. - please refer to Figures 1 and 2. ITS As part of the proposal, parking structures will be equipped with sensors monitoring in real time the degree of occupancy of each sector and reverting this in- formtaion and other diagnostics back to the control room of the MBCC. This will result in a set of Variable Mes- sange Panels (VMP) which will be locoated along the perimetral roads of the MBCC advising drivers on park- ing availability and status. These can also be considered proper ITS devices and can be assumed as the first step of a broader strategy for dynamic wayfing which could be used in the future to provide information on traffic conditions and advise motorists on the proper route to reach the MBCC.

However, digital panels located as far as the causeways require a full network of sensors and a centralized traffic control unit which can only be integrated in the city in- frsatructure. This also applies to real-time monitoring of public transport vehicles location in relation to the infor- mation distributed to passengers through applications or latest generation bus stops panels. All these layers of technology rely on protocols which require integration from a supervising entity in order to operate seamlessly. This is the reason for having to necessarily rely on the involvement of City Administration to address this wider strategy prior to contributing to it. All this provided, it is deemed that contribution from ITS and other forms of digital technology can ease the mo- bility of motorists and people in general and it is highly recommended that actions are taken in this direction.Washigton Av.Meridian Av.Dade Bl v. 17th street Washigton Av.Meridian Av.Dade Bl v. 17th street Exhibit 7Publicly Funded Open Space Areas 62 South Beach ACE Letter of Intent Circulation Plan - Goods Vehicles Similarly to the private traffic, goods vehicles are planned to follow the same strategy: • The main flow of goods vehicles is related to the operation of the MBCC and will access the site from Dade Blvd., exploiting the length of Convention Center Drive to orderly proceed towards the gate of the loading area at the north end of the halls. This will mainly occur during move-in and move-out days. • The secondary flow of goods vehicles is related to the hotel and its loading facility located underneath the concourse next to the lobby. The entry to the facility is either from Convention Center Drive or Figure 4 - Proposed entrance/exit sequence for loading facilities Circulation Plan - Buses In terms of buses circulation and drop-off, the proposed operational and geometric scheme makes allowance for the stacking of up to 25 buses divided in two facilities: • along the western edge of Hall C, and • along the southern facade next to the meeting rooms. The double kerb offers the possibility to better distribute the flows and occasionally to close Convention Center Drive for events without imèairing the functionality of the facility. Drop-off Way in Way out Figure 3 - Proposed entrance/exit sequence of Buses Meridian Av. and, as per the valet, through the roundabout and the ramp beneath the landscaped berm down to the lower level. Vehicles entering from Meridian Av. can reach the ramp without circulating in front of the hotel's main entrance and drop-off. • Finally, the loading area of the Jackie Gleason Theater will be accessed from the drop-off along 18th street. Summary of proposals The main modifications on the existing road network can be summarized in three major topics: • pedestrian safety • seamless integration with public transport facilities, and • protection of adjacent residential neighborhoods from through traffic heading to/coming from the Miami Beach Convention Center. The primary objective is reached by introducing: • a landscaped median along 17th street providing a safe space for pedestrians who can't complete the crossing; • a pedestrian-only traffic light along 17th street in combination with the proposed crossings in the me- dian and adjacent to the newly proposed/relocated bus stops; • a pedestrian.only traffic light along 17th street in as- sociation with the connection to Soundscape Park;Washigton Av.Meridian Av.Dade Bl v. 17th streetWashigton Av.Meridian Av.Dade Bl v. 17th street Exhibit 7Publicly Funded Open Space Areas 63 South Beach ACE Letter of Intent • a traffic signal with associated pedestrian crossing along Meridian Av. at the crossing with 18th street; • a pedestrian crossing ensuring continuity along Dade Boulevard @ Meridian Av. In second place, the integration with the public transport service is ensured by relocation and, where necessary, addition of bus stops in the vicinity of the MBCC. In particular a bus stop was added along 17th street at the corner with Pennsylvania Av. in order to facilitate the accessibility of those arriving by transit, and also to engage such flows in the public pedestrian space at the south of the Convention Center. Furthermore, the consciousness of the potential devel- opment of transit within South Beach as envisaged by several planning documents and studies, led the design of the masterplan public realm. Being accessible on three out of four sides, the plan is flexible in receiving flows of passengers from either the southern (17th street) as well as the eastern side (Wash- ington Av.) whenever decisions will be made at higher levels of Public Administration on the routing of the so- called Bay Link. Currently, the plan shows the provision for bus stops with dedicated lay-bys along 17th street, Meridian Av and Washingtoin Av.

This traffic is the main cause of excessive speeding, aggres- sive driving, but also noise and pollution for the residents of Palm View and Bayshore. It is believed that only a physical barrier can ensure the level of enforcement required for this strategy and for this purpose two controlled accesses are proposed along 18th street and 19th street in the first block west of Meridian. These controlled locations will automatically filter vehicular traffic demanding to cross the neighbor- hood in relation to the possession of permit released by the municipality. Accordingly, • the residents will continue experiencing the same ac- cessibility to their homes as today; • the non residents will be prevented from travelling RFID antenna – INBOUND/OUTBOUND Bollard/Physical barrier. ECU/Control Unit – coordinates RFIDs response and triggers the mechanics of the bollards.

FIGURE 6 - Below a diagram representing the potential layout of the gates along Meridian Avenue. through the neighborhood (as a shortcut); • access to the properties by non-residents will still be granted freely and at all times by accesses along 17th (Lenox, Michigan, Jefferson) which is deemed acceptable in relation to the advantages. This strategy is based on the implementation of barriers (mainly pneumatic bollards) equipped with RFID tech- nology sensors which will recognize and give access to vehicles of Palm View residents while inhibiting through traffic in the neighborhood. This system does not require connection to a remote da- tabase of authorized vehicles and it can be considered a proper wlocalized intelligence unit that doesn’t require city-wide infrastructure to be implemented. For this very reason it is readily implementable and ef- fective from day one. The same concept is proposed for Bayshore where the gate is proposed on Prairie Av. @ W 28th Street. 3 2 4 1 3 4 1 3 2 1 4 Exhibit 7Publicly Funded Open Space Areas 65 South Beach ACE Letter of Intent XX MONTH 2012 / pgProf. Dennis Frenchman & Prof. Carlo Ratti with EXISTING CONDITION •Scenario 1 – 2013 condition with event → 20455 veh/3h •Scenario 2 – 2013 condition without event→ 20237 veh/3h PROJECT •Scenario 3 ‐Project Scenario without additional traffic → 20237 veh/3h •Scenario 4 –Project Scenario with traffic produced by event → 22671 veh/3h •Scenario 5 –Project Scenario with traffic produced by event and signal optimization → 22671 veh/3h Traffic Model All the proposed intervetions on the road network were assessed by means of a traffic microsimulation model which enabled a real-time assessment of the traffic con- ditions across the entire network enclosed in the study area. This technique was chosen as it enables the assess- ment of the mutual effects of conditions at adjacent junctions. This allows, for example, evaluating the presence of back-blocking phenomena of intersections downstream as, for instance, the case of the intersection between Alton Rd and Dade vs. the intersection between Alton Rd and 17th Street. It is well known that the traffic problems at the former are dictated by lack of perfor- mance at the latter. An extensive traffic survey exercise was carried out dur- ing two weeks in the month of February 2013 during and after the Boat Show 2013, thus providing the team with the necessary information to develop the model. Figure 7 - Diagram of the modelled road network within the study area in the existing (left) and proposed scenario (right) Traffic Analysis Zone Parking zone Traffic Analysis Zone Parking zone New MBCC zone Existing condition scenario The existing condition scenario addresses the cur- rent road newtork layout (i.e. current scheme, current arrangement of bus stops, traffic signals, pedestrian crossings etc...) against two situations: with and without events taking place at the MBCC. In the full traffic report technical details about the calibra- tion and validation of the model can be found. Project scenario The Project Scenarios are evaluated by introducing one step at a time the modifications to either the road net- work and the amount of traffic estimated. These are: • Road network as per the revised geometry + traffic as conditions without event; • Road network as per the revised geometry + traffic as conditions with event and additional program; • Road network as per the revised geometry + traf- fic as conditions with event and additional program + traffic signal optimization (i.e. with the proposed mitigation measures).

This inlcudes: • 633,730 sqf of hotel space, • 447,000 sqf of residential space, and • nearly 100,000 sqf or retail space of which 59,500 sqf concentrated on 17th street at Pennsylvania Av. The amount of traffic added on the road network and due to the additional program is: • 216 veh/h in the AM peak, and • 422 veh/h in the PM as a bi-directional value. The amount of traffic added on the road network and due to the activity of the MBCC is: • 1460 veh/h in the AM peak, and • 1422 veh/h in the PM peak.

With reference to the chart and table here below, the behavior of the network can be explained: 1. The existing condition with event operates at a mean speed value of 12.3 mph (includes time spent in line, time spent at the traffic lights etc...) which improves to 13.8 mph (+12%) when events are not in place. 2. The modifications to the road network induced by the MBCC, excluding the traffic signal optimization (e.i. with the same traffic signals as of today), shows a decrement of the performance of the network of 11.5% 3. Scenario n° 4, featuring the proposed road network with the total additional traffic, but without traffic sig- nal optimization produces a significant loss in per- formance reaching values of 4.3 mph and inducing queues beyond the extent of the study area (i.e. 8% of the vehicles demanding to enter the study area don't manage to do so and are queuing outside). 4. Finally, the proposed traffic signal optimization is introduced in Scenario n°5 showing traffic perfor- mances similar to the existing condition; 12.0 mph vs 12.3 mph (i.e. a negligible decrease of only 2%).

EXISTING CONDITION PROJECT CONDITION In other words, the proposed strategy, manages to offset completely the impacts of the additional traffic related to the proposed program and MBCC operation during an event. The Figures 9 and 10 below also show in a diagrammatic form the existing condition vs the proposed optimized project condition in terms of queues distribution (Fig. 9) and traffic flows (Fig.10) on the road network. It is clearly evincible the effect of displacement of traffic from 17th street toward Dade, as desired, with the con- sequential benefit for 17th Street current congestion. Comparing the project and the existing condition, it is noted that queues at intersections along 17th Street reduce while they slightly increase along Dade.0-200201-300301-400401-500501-600601-700701-800801-900901-10001001-2000Vehicle /h EXISTING CONDITION PROJECT CONDITION Similarly, the traffic flows are shifted north from the exits of the car park on Convention Center Drive and Wash- ington Avenue. Also, from the diagram of the project scenario it is noted that the internal valet circuit operates with flows lower than 200 veh/h which is compatible with the concept of pedestrian friendliness that inspired the shared public space. Meridian Avenue, which bears all traffic to/from the Hotel and the Residential program is also operating with flows lower than 500 veh/h similarly to the existing condition, thus suggesting that the impact is offset. The full traffic report with all the details on the calculation of trips and the modelling process will be issued on May 13th, 2013.
